Book excerpt: The millimeter wave to THz region (0.1 - 1 THz) of the electromagnetic spectrum possesses unique properties which lead to potential applications ranging from non-intrusive security, high data rate communications, medical imaging, and industrial quality control. However, the unavailability of oscillators/amplifiers with adequate power in a compact package has led to the expression "THz Gap". Microwave Vacuum Electron Device (MVED) technology is considered by many to be the most promising approach for a THz source. The main focus of this dissertation has been in conjunction with the DARPA (Defense Advanced Research Project Agency) HiFIVE (High Frequency Integrated Vacuum Electronics) 220 GHz program. Some supportive work has also been conducted in support of W-band Sheet Beam Klystron and 94 GHz Gyrotron development efforts. A complete MEMS (micro-electro-mechanical-systems) process was developed to precision fabricate micro-metallic staggered vane waveguides 400 [mu]m tall and with the shortest cavity of 75 [mu]m in a single layer process. MEMS fabricated 220 GHz, Traveling Wave Tube Amplifier (TWTA) circuits were demonstrated with unprecedented results of RF transmission S21 ~ - 6 dB in a pass band 214 - 266 GHz, corresponding to a bandwidth > 50 GHz. 3D electromagnetic wave, particle dynamics and beam-wave interaction simulation codes were utilized for realistic device design and modeling of fabrication errors. Cold test measurements were conducted in the frequency range 160 - 280 GHz to characterize the TWT circuits using both a backward wave oscillator based scalar network analyzer and Agilent PNA-X. Hot test experiments were conducted for the 220 GHz TWTA with (a) no RF input, for zero drive stability analysis and (b) with RF drive. Millimeter wave frequency and power calibration/measurement techniques were employed to analyze the lower (2[pi])/upper (3[pi]) cutoff oscillations. TWTA gain was measured as a function of frequency and collector current. For the next generation compact, PCM (permanent cusp magnet) integrated TWTA approach, the complete assembly, including 220 GHz TWT circuit (19.5 kV, 200 mA), permanent magnets (NdFeB) based sheet beam transport, and RF windows was designed. The Nano-CNC fabrication has been completed and PCM is being assembled.

Gilmour, Jr. and published by Artech House. This book was released on 2020-04-30 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by an internationally recognized as an expert on the subject of microwave (MW) tubes, this book presents and describes the many types of microwave tubes, and despite competition from solid-state devices (those using GaN, SiC, et cetera), which continue to be used widely and find new applications in defense, communications, medical, and industrial drying. Helix traveling wave tubes (TWTs), as well as coupled cavity TWTs are covered. Klystrons, and how they work, are described, along with the physics behind it and examples of devices and their uses. Vacuum electron devices are explained in detail and examines the harsh environment that must exist in tubes if they are to operate properly. The secondary emission process and its role in the operation of crossed-field devices is also discussed. The design of collectors for linear-beam tubes, including power dissipation and power recovery, are explored. Discussions of important noise sources and techniques that can be used to minimize their effects are also included. Presented in full color, this book contains a balance of practical and theoretical material so that those new to microwave tubes as well as experienced microwave tube technicians, engineers, and managers can benefit from its use.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: With the emergence of high power, millimeter wave sources operating at 94 GHz and 220 GHz with output powers in excess of 10 kW and 50 W, respectively, creates a critical need to route and process these powers efficiently. Since fundamental mode waveguides become unreasonably lossy and run into the breakdown regime to handle these associated powers when operating at the millimeter wave to terahertz regime, quasi-optical techniques, which utilize higher beam modes and common optical techniques, are employed. Such techniques typically require stringent mode control and call for intercoupling wave propagation analysis to minimize mode conversion. These complicated analysis techniques stretch the capabilities of traditional differential equation formulations typically employed to analysis complex structures in the microwave regime. Additionally, these structures become electrically large due to the shrinking associated wavelengths of the propagating waves in the millimeter wave to terahertz spectrum making such analysis difficult-to-impossible under 'normal' computing conditions. To intelligently design and manufacture these components, the multiphysics behavior of these devices must be carefully understood. As a result, circuit models and quick solver methodologies are presented and used to analyze these electrically large systems. As a result of careful signal integrity engineering, quasi-optical components and systems are designed and the experimental results are presented to extract empirical values, benchmark numerical solutions, and for practical use. As a result of these studies, one can conclude that quasi-optical signal processing and overmoded transmission line systems are essential to efficiently process the high powers fields radiating from the described vacuum electron beam devices for next generation telecommunication, remote sensing, scientific instrumentation, and electronic warfare systems.

Available in PDF, EPUB and Kindle. Book excerpt: The millimeter-wave (MMW) and terahertz (THz)-regime portions of the electromagnetic spectrum have enormous application potential, including high-data-rate communications, remote sensing and threat detection, high resolution radar, biomedical imaging, and spectroscopic analysis. To exploit this potential, new sources of coherent electromagnetic radiation are needed in the frequency range of 100 - 1000 GHz. The ideal sources would provide high power with high efficiency in a compact, lightweight, and low-cost package. Many of the applications require bandwidths of several percent (relative) or greater and both amplifiers and oscillators are needed. Vacuum electronic devices, such as traveling wave tubes (TWTs) meet many of these requirements but are constrained by complex fabrication methods that become impractical at frequencies of 100 GHz and above. This research is investigating new methods for TWT fabrication, derived from semiconductor microfabrication technologies. Various microfabrication techniques are under investigation, to identify those that are optimally suited. One critical piece of research is to measure the passive microwave losses of a 400 GHz waveguide made by these microfabrication methods. The final goal includes a study of the characteristics of a microfabricated TWT using a new electron-beam source designed for MMW and THz-regime vacuum device research.

Available in PDF, EPUB and Kindle. Book excerpt: The book describes distinctive features of the terahertz radiation interaction with various materials, including the Earth’s atmosphere, liquids, dielectrics, superconductors, semiconductors, metals and 2D-structures. It discusses all types of terahertz sources, including lasers, photoconductive antennas, semiconductor diode and transistor generators and amplifiers, and considers terahertz band vacuum devices. The text offers a comparative analysis of these devices and their perspectivity in the terahertz band, and describes the basic types of terahertz detectors. Also investigated here are the reasons for the appearance of the so-called “terahertz gap” and the means of increasing working frequency and output power of the sources of terahertz radiation. The book also considers the electromagnetics and electron-optical systems of vacuum terahertz devices and their manufacturing technology.
