Available in PDF, EPUB and Kindle. Book excerpt: Metamaterials, materials that are constructed with arrays of small elements have significant potential to provide material properties that are useful for electromagnetic applications but are not found in nature. Slight changes to a repeated unit cell can be used to tune the effective bulk material properties of a metamaterial, replacing the need to discover suitable materials for an application with the ability to design a structure for the desired effect. However, most current metamaterial realizations are plagued by high loss, large size, awkward structure, or difficult construction. The use of Micro-Electro-Mechanical Systems (MEMS) to create a new metamaterial could improve upon some of these shortcomings due to their small size, high Q. and ease of integration into standard applications and circuit fabrication techniques. In this thesis. I analyze the prospects of a MEMS-based metamaterial. First, I determine the best type of MEMS resonator to use in a metamaterial. Then, I build models that can accurately describe a metamaterial constructed of MEMS unit cells. Analysis of these models provides information about the potential behavior of a MEMS metamaterial. It is discovered that it is possible to create a left-handed metamaterial using MEMS resonators. Finally, phase-shifting and antenna miniaturization applications are suggested as potential areas that can leverage the benefits of this new MEMS metamaterial.

Download or read book MEMS Field Models and Optimal Design written by Paolo Di Barba and published by Springer. This book was released on 2019-06-26 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights numerical models as powerful tools for the optimal design of Micro-Electro-Mechanical Systems (MEMS). Most MEMS experts have a background in electronics, where circuit models or behavioral models (i.e. lumped-parameter models) of devices are preferred to field models. This is certainly convenient in terms of preliminary design, e.g. in the prototyping stage. However, design optimization should also take into account fine-sizing effects on device behavior and therefore be based on distributed-parameter models, such as finite-element models. The book shows how the combination of automated optimal design and field-based models can produce powerful design toolboxes for MEMS. It especially focuses on illustrating theoretical concepts with practical examples, fostering comprehension through a problem-solving approach. By comparing the results obtained using different methods, readers will learn to identify their respective strengths and weaknesses. In addition, special emphasis is given to evolutionary computing and nature-inspired optimization strategies, the effectiveness of which has already been amply demonstrated. Given its scope, the book provides PhD students, researchers and professionals in the area of computer-aided analysis with a comprehensive, yet concise and practice-oriented guide to MEMS design and optimization. To benefit most from the book, readers should have a basic grasp of electromagnetism, vector analysis and numerical methods.

Book excerpt: This book presents the proceedings of the 4th International Conference on Internet of Things and Connected Technologies (ICIoTCT), held on May 9–10, 2019, at Malaviya National Institute of Technology (MNIT), Jaipur, India. The Internet of Things (IoT) promises to usher in a revolutionary, fully interconnected “smart” world, with relationships between objects and their environment and objects and people becoming more tightly intertwined. The prospect of the Internet of Things as a ubiquitous array of devices bound to the Internet could fundamentally change how people think about what it means to be “online”. The ICIotCT 2019 conference provided a platform to discuss advances in Internet of Things (IoT) and connected technologies, such as various protocols and standards. It also offered participants the opportunity to interact with experts through keynote talks, paper presentations and discussions, and as such stimulated research. With the recent adoption of a variety of enabling wireless communication technologies, like RFID tags, BLE, ZigBee, embedded sensor and actuator nodes, and various protocols such as CoAP, MQTT and DNS, IoT has moved on from its infancy. Today smart sensors can collaborate directly with machines to automate decision-making or to control a task without human involvement. Further, smart technologies, including green electronics, green radios, fuzzy neural approaches, and intelligent signal processing techniques play an important role in the development of the wearable healthcare devices.

Download or read book Information Metamaterials written by Tie Jun Cui and published by Cambridge University Press. This book was released on 2021-02-18 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metamaterials have attracted enormous interests from both physics and engineering communities in the past 20 years, owing to their powerful ability in manipulating electromagnetic waves. However, the functionalities of traditional metamaterials are fixed at the time of fabrication. To control the EM waves dynamically, active components are introduced to the meta-atoms, yielding active metamaterials. Recently, a special kind of active metamaterials, digital coding and programmable metamaterials, are proposed, which can achieve dynamically controllable functionalities using field programmable gate array (FPGA). Most importantly, the digital coding representations of metamaterials set up a bridge between the digital world and physical world, and allow metamaterials to process digital information directly, leading to information metamaterials. In this Element, we review the evolution of information metamaterials, mainly focusing on their basic concepts, design principles, fabrication techniques, experimental measurement and potential applications. Future developments of information metamaterials are also envisioned.
