"The increasing commercial use of millimeter wavelengths for remote sensing, communications, and radar systems has driven the need for new low-cost, high performance systems, and with it, the need for quasioptical systems.Combining a general introduction to Gaussian beams and quasioptical propagation with practical applications, QUASIOPTICAL SYSTEMS provides a state-of-the-art treatment of the design of low-loss, broadband systems at microwave to submillimeter wavelegnths. the approach presented involved utilizing a beam with a Gaussian distribution of field strength perpendicular to its axis, which in turn propagates in a simple predictable fashion. Features include: A Convenient summary of Gaussian beam propagation formulas; Extensive coverage of present-day quasioptical components and their performance; In-depth coverage of dielectric material uses at millimeter and submillimeter wavelengths; An analysis of lenses and mirrors together with design techniques; and much more!This book will be of key interest to systems designers, antenna engineers, communications systems engineers, and researchers."

Over the past two decades, submillimeter and terahertz astronomy has grown rapidly and become an important new window for studying the universe. This growth has been enabled by the confluence of several technologies which make the design and fabrication of high frequency single and multi-pixel heterodyne receivers possible. This dissertation reviews the development of a new generation of terahertz instrumentation at the University of Arizona, with specific emphasis on their optical components and systems. These instruments include several receivers for the Antarctic Submillimeter Telescope and Remote Observatory (formerly installed at the South Pole), including a dual-frequency 492/810 GHz receiver called Wanda, a 4-pixel 810 GHz heterodyne array called PoleSTAR, and a 1.5 THz receiver called TREND. It also covers receivers for the Heinrich Hertz Submillimeter Telescope on Mt. Graham in southern Arizona. These receivers include a 7-pixel 345 GHz heterodyne array called DesertSTAR, a 64-pixel polarimeter/bolometer system called Hertz, and a 64-pixel 345 GHz heterodyne array called SuperCam. After reviewing these instruments, concepts for the next generation of arrays and terahertz telescopes designed for the high Atacama desert, Antarctica, high altitude balloon missions, and orbiting observatories will be presented. This dissertation will also cover other contributions made to terahertz astronomy, including the creation of a Gaussian beam propagation program to help design terahertz optical systems and an integrated optics design for a waveguide interferometer to be used as an alternative to traditional bulk optics systems.

This report documents the development of of a number of techniques for the computer aided analysis of quasioptical power combining systems. The major results of the project were the development of models for IMPATT diodes suitable for harmonic balance analysis and transient analysis; the development of quasioptical Green's functions for cavity resonators and grid systems; the development of a Method of Moments code which can use the mixed scalar potential and vector Green's function developed for quasioptical systems; a transient analysis engine for quasioptical systems and developments of an harmonic balance technique suitable for quasioptical systems. The work makes a broader contribution to the computer ailded engineering of microwave and millimeter wave systems with complex device field interactions.
