Download or read book New Type of sub THz Oscillator and Amplifier Systems Based on Helical Type Gyro TWTs written by Marek, Alexander and published by KIT Scientific Publishing. This book was released on 2023-01-26 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents the development of a new sub-THz source for the generation of trains of coherent high-power ultra-short pulses at 263 GHz via passive mode-locking of two coupled helical gyro-TWTs. For the first time, it is shown that the operation of such passive mode-locked helical gyro-TWTs in the hard excitation regime is of particular importance to reach the optimal coherency of the generated pulses. This could be of particular interest for some new time-domain DNP-NMR methods.

Book excerpt: Microwave photonics continues to see rapid growth. The integration of optical fiber and wireless networks has become a commercial reality and is becoming increasingly pervasive. Such hybrid technology will lead to many innovative applications, including backhaul solutions for mobile networks and ultrabroadband wireless networks that can provide users with very high bandwidth services. Microwave Photonics, Second Edition systematically introduces important technologies and applications in this emerging field. It also reviews recent advances in micro- and millimeter-wavelength and terahertz-frequency systems. The book features contributions by leading international researchers, many of whom are pioneers in the field. They examine wave generation, measurement, detection, control, and propagation in detail, as well as the devices and components that enable ultrawide-band and ultrafast transmission, switching, and signal processing. These devices and components include optical-controlled microwave devices, optical transmitters, receivers, switching devices, detectors, and modulators. The book explores the theory, techniques, and technologies that are fueling applications such as radio-over-fiber, injection-locked semiconductor lasers, and terahertz photonics. Throughout, the contributors share insights on overcoming current limitations and on potential developments. What’s New in This Edition Two new chapters, on fiber Bragg gratings for microwave photonics applications and ultrawide-band sub-THz photonic wireless links Updates throughout, reflecting advances in the field New illustrations in each chapter Fully illustrated with more than 300 figures and tables, this book offers a detailed, wide-ranging overview of the current state and future directions of this burgeoning technology.

Download or read book RF and Time domain Techniques for Evaluating Novel Semiconductor Transistors written by Keith A. Jenkins and published by Springer Nature. This book was released on 2021-12-15 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a variety of techniques using high-frequency (RF) and time-domain measurements to understand the electrical performance of novel, modern transistors made of materials such as graphene, carbon nanotubes, and silicon-on-insulator, and using new transistor structures. The author explains how to use conventional RF and time- domain measurements to characterize the performance of the transistors. In addition, he explains how novel transistors may be subject to effects such as self-heating, period-dependent output, non-linearity, susceptibility to short-term degradation, DC-invisible structural defects, and a different response to DC and transient inputs. Readers will understand that in order to fully understand and characterize the behavior of a novel transistor, there is an arsenal of dynamic techniques available. In addition to abstract concepts, the reader will learn of practical tips required to achieve meaningful measurements, and will understand the relationship between these measurements and traditional, conventional DC characteristics.

Download or read book Advanced DSP Techniques for High Capacity and Energy Efficient Optical Fiber Communications written by Zhongqi Pan and published by MDPI. This book was released on 2019-12-03 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid proliferation of the Internet has been driving communication networks closer and closer to their limits, while available bandwidth is disappearing due to an ever-increasing network load. Over the past decade, optical fiber communication technology has increased per fiber data rate from 10 Tb/s to exceeding 10 Pb/s. The major explosion came after the maturity of coherent detection and advanced digital signal processing (DSP). DSP has played a critical role in accommodating channel impairments mitigation, enabling advanced modulation formats for spectral efficiency transmission and realizing flexible bandwidth. This book aims to explore novel, advanced DSP techniques to enable multi-Tb/s/channel optical transmission to address pressing bandwidth and power-efficiency demands. It provides state-of-the-art advances and future perspectives of DSP as well.
