Download or read book Simulation driven Design Optimization And Modeling For Microwave Engineering written by Qi-jun Zhang and published by World Scientific. This book was released on 2013-03-14 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer-aided full-wave electromagnetic (EM) analysis has been used in microwave engineering for the past decade. Initially, its main application area was design verification. Today, EM-simulation-driven optimization and design closure become increasingly important due to the complexity of microwave structures and increasing demands for accuracy. In many situations, theoretical models of microwave structures can only be used to yield the initial designs that need to be further fine-tuned to meet given performance requirements. In addition, EM-based design is a must for a growing number of microwave devices such as ultra-wideband (UWB) antennas, dielectric resonator antennas and substrate-integrated circuits. For circuits like these, no design-ready theoretical models are available, so design improvement can only be obtained through geometry adjustments based on repetitive, time-consuming simulations. On the other hand, various interactions between microwave devices and their environment, such as feeding structures and housing, must be taken into account, and this is only possible through full-wave EM analysis.Electromagnetic simulations can be highly accurate, but they tend to be computationally expensive. Therefore, practical design optimization methods have to be computationally efficient, so that the number of CPU-intensive high-fidelity EM simulations is reduced as much as possible during the design process. For the same reasons, techniques for creating fast yet accurate models of microwave structures become crucially important.In this edited book, the authors strive to review the state-of-the-art simulation-driven microwave design optimization and modeling. A group of international experts specialized in various aspects of microwave computer-aided design summarize and review a wide range of the latest developments and real-world applications. Topics include conventional and surrogate-based design optimization techniques, methods exploiting adjoint sensitivity, simulation-based tuning, space mapping, and several modeling methodologies, such as artificial neural networks and kriging. Applications and case studies include microwave filters, antennas, substrate integrated structures and various active components and circuits. The book also contains a few introductory chapters highlighting the fundamentals of optimization and modeling, gradient-based and derivative-free algorithms, metaheuristics, and surrogate-based optimization techniques, as well as finite difference and finite element methods./a

Download or read book Co simulations of Microwave Circuits and High Frequency Electromagnetic Fields written by Mei Song Tong and published by Springer. This book was released on 2024-03-10 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to provide many advanced application topics for microwave circuits and high-frequency electromagnetic (EM) fields by using advanced design system (ADS) and high-frequency structure simulator (HFSS) as simulation platforms. In particular, it contains the latest multidisciplinary co-simulation guidance on the design of relevant components and devices. Currently, the circuit/field design and performance analysis and optimization strongly rely on various kinds of robust electronic design automation (EDA) software. RF/microwave engineers must grasp two or more types of related simulation design software. ADS by Keysight and HFSS by Ansys are the representative for circuit simulations and for field and structural simulations of microwave devices, respectively. At present, these two types of software are widely used in enterprises, universities, and research institutions. The main purpose of this book is to enable readers, who are interested in microwave engineering and applied electromagnetics, to master the applications of these two tools. It also helps readers expand their knowledge boundaries behind those types of software and deepen their understanding of developing interdisciplinary technologies by co-simulations. The book is divided into three parts. The first part introduces the two latest versions of ADS and HFSS and helps readers better understand the basic principles and latest functions better. It also advises how to choose appropriate simulation tools for different problems. The second part mainly describes co-simulations for high-frequency EM fields, microwave circuits, antenna designs, EM compatibility (EMC), and thermal and structural analyses. It provides guides and advices on performing co-simulations by ADS and HFSS incorporated with other types of software, respectively. The last part narrates the automation interfaces and script programming methods for co-simulations. It primarily deals with the Advanced Extension Language (AEL), Python Data Link (PDL), and MATLAB interface in ADS. For HFSS, it discusses VBScript, IronPython scripting, and Application Programming Interface (APIs) based on MATLAB. Each topic contains practical examples to help readers understand so that they can gain a solid knowledge and skills regarding automated interfaces and scripting methods based on these kinds of software. Concisely written in combination with practical examples, this book is very suitable as a textbook in introductory courses on microwave circuit and EM simulations and also as a supplementary textbook in many courses on electronics, microwave engineering, communication engineering, and related fields. As well, it can serve as a reference book for microwave engineers and researchers.
Download or read book Tuning Techniques for Microwave Devices Based on Space Mapping and Surrogate Modeling written by Song Li and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a modern wireless communication system, with the development of various applications, microwave filters with stringent specifications and tunability start to receive more attention. Advances in novel materials, fabrication techniques, filter structures, tuning techniques, full-wave electromagnetic analysis methods, and computer-aided (CAD) design tools are proposed and delivered in the past 20 years. A designer can accurately model, simulate and optimize a filter structure with the use of different commercial software. Nevertheless, the experimental results from a fabricated filter usually give different performance compared to theoretical models and electromagnetic (EM) simulations due to many kinds of variations like fabrication process variation, assembly tolerances, inherent cross-couplings, run-time thermal variation, and parasitic in components that make up the tuning circuits. Hence, a fabricated filter generally requires a tuning process to compensate for the variations and improve the performance. In the filter industry, the tuning process becomes one of the most significant steps for the production of commercial filters. The work presented in this thesis focuses on developing novel design and tuning methods that can be used to enhance the tuning process of a tunable filter, improve the efficiency of the post-fabrication tuning process in filter production, and develop methods for real-time load matching. This work proposes two methods for post-fabrication tuning of microwave bandpass filters. The first method uses the space mapping technique and sensitivity analysis. It is applied to tune a varactor-tuned microstrip filter fabricated using FR-4 with uncertain dielectric constant and quality factor. Good tuning results are obtained by using the proposed method. The second method is an advanced surrogate-based post-fabrication tuning method, which is proved to be more accurate and reliable. In this method, a novel recursive multipoint calibration process is introduced to solve the main problem that existed in the first method, which is the non-uniqueness problem. Three post-fabrication tuning examples, including a conventional iris-coupled waveguide filter fabricated by CNC, a 3D printed waveguide filter with high alignment tolerance and surface roughness, and the varactor-tuned microstrip filter are given to validate the accuracy and efficiency of the proposed method. Comparisons between the proposed surrogate-based method and existing filter tuning methods are illustrated. The proposed surrogate-based method is proved to be very efficient and reliable for post-fabrication tuning of microwave bandpass filters. The space mapping and surrogate modeling techniques are also applied to the tuning of the impedance matching network. In this thesis, two tuning methods, including a surrogate-based tuning method, and a sequential aggressive space mapping tuning method are presented in detail for tuning of the triple-stub tuner, which is a tunable device widely used for high-power applications. An automated tuning system is implemented and tested to validate the accuracy and efficiency of the proposed method.
