The thesis describes the development of receiver technologies for sub-millimetre astronomy instruments, focusing on high performance coherent cryogenic detectors operating close to the superconductor gap frequency. The mixer chip which comprises the SIS devices, fed by a unilateral finline and matching planar circuits was fabricated on 15 micron silicon substrate using the recently developed Silicon-On-Insulator (SOI) technology. This offered broadband IF and RF performance, with fully integrated on-chip planar circuits resulting in an easily reproducible mixer chip and a simple mixer block. An important consequence of this design is that it can be extended to the supra-THz region and making the fabrication of multi-pixel heterodyne arrays feasible. The extension of the operation of major telescopes such as ALMA, APEX and the GLT from single pixel to large format arrays is the subject of extensive research at present time since it will allow fast mapping combined with high resolution of the submillimetre sky. The technology described in this thesis makes a major contribution to this effort.
The Handbook of Applied Superconductivity, Two-Volume Set covers all important aspects of applied superconductivity and the supporting low-temperature technologies. The handbook clearly demonstrates the capabilities of superconducting technologies and illustrates how to implement these technologies in new areas of academic and industrial research and development. Volume One provides an introduction to the theoretical background of both low and high Tc superconductivity, followed by details of the basic hardware such as wires, tapes, and cables used in applications of superconductivity and the necessary supporting science and technology. Theoretical discussions are in most cases followed by examples of real designs, fabrication techniques, and practical instrumentation guidance. A final chapter examines materials properties at low temperatures. Volume Two provides examples of current and future applications of superconductivity. It covers medical systems for magnetic resonance imaging (MRI), high field magnets for research, superconducting magnets for accelerators, industrial systems for magnetic separation, and transportation systems. The final chapters look to future applications in power and superconducting electronics. With fully referenced, peer-refereed contributions from experts in various fields, this two-volume work is an essential reference for a wide range of scientists and engineers in academic and industrial research and development environments.
A description of field-theoretical methods for the design and analysis of planar waveguide structures and antennas. The principles and limitations of transit-time devices with different injection mechanisms are covered, as are aspects of fabrication and characterization. The physical properties of silicon Schottky contacts and diodes are treated in a separate chapter, while two whole chapters are devoted to silicon/germanium devices. The integration of devices in monolithic circuits is explained together with advanced technologies, such as the self-mixing oscillator operation, before concluding with sensor and system applications.
Infrared and Millimeter Waves, Volume 15: Millimeter Components and Techniques, Part VI is concerned with millimeter-wave guided propagation and integrated circuits. This book covers low-noise receiver technology for near-millimeter wavelengths; dielectric image-line antennas; EHF satellite communications (SATCOM) terminal antennas; and semiconductor antennas for millimeter-wave integrated circuits. A scanning airborne radiometer for 30 and 90 GHz and a self-oscillating mixer are also described. This monograph is comprised of six chapters and begins with a discussion on the design of low-noise receivers, with emphasis on problems encountered at near-millimeter wavelengths. Optimization of the material parameters and device topology for both Schottky-barrier diodes and superconducting mixer elements are considered. Some representative examples of state-of-the-art mixers and receivers, designed to operate at frequencies of 100-1000 GHz, are given in order to illustrate the way in which practical, high-performance millimeter-wave devices can be constructed. The following chapters focus on a scanning airborne radiometer for 30 and 90 GHz; a self-oscillating mixer; dielectric image-line antennas; and EHF SATCOM terminal antennas. The final chapter is devoted to semiconductor dipole antennas for millimeter-wave sensors, with particular reference to the basic concepts leading to the development of semiconductor dipoles. A theoretical formulation for tubular semiconductor dipoles is outlined and numerical results are presented to assess their characteristics. This text will be a valuable resource for physicists and electronics and electrical engineers.
