UNIFIED MICROWAVE NETWORK THEORY BASED ON CLIFFORD ALGEBRA IN LORENTZ SPACE f E F Bol inder* ABSTRACT A unified network theory is presented. It consists of three parts: a network formal ization, a geometrical model, which is the Minkowski model of Lorentz space, and a mathematical tool, Clifford algebra. The latter is well suited in deal ing with rotations in Lorentz space. The rotati

QUASIOPTICS IN MILLIMETERWAVE SYSTEMS Paul F. Goldsmith * ABSTRACT We give a review of certain aspects of quasioptical techniques applied to millimeter wavelength systems. We summarize the results of theory of Gaussian beam propagation, and describe in particular ho~ dielectric materials can perform useful system functions, acting as directional couplers, hybrids, filters, and diplexers.

MICROWAVE RADIOMETRY IN REMOTE SENSING P. Gudmandsen* ABSTRACT Microwave radiometry has shown its capabilities of observing and monitoring large-scale geophysical observables from space. Examples are sea surface temperature and surface wind over the ocean, sea ice extent, concentration and category and snow cover extent and water content. At low microwave frequencies the atmosphere is virtual

MULTILAYER CANONICAL WAVE STRUCTURES RANGE FOR NONRECIPROCAL DEVICES IN THE SUBMILLIMETER Donald M. Bolle and Salvador H. Talisa ABSTRACT Dispersion and loss characteristics are presented for a canonical fiveregion structure modelling surface magnetoplasmon based nonreciprocal devices in the millimeter and submillimeter wave range. Our results are based on an exact analysis of the model

COMPARATIVE FM NOISE OF FREE-RUNNING OR PHASE-LOCKED FREQUENCY M.R. MULTIPLIERS FRISCOURT, IN THE 94 GHz REGION E. CONSTANT GUNN OSCILLATOR AND AVALANCHE P.A. ROLLAND, G. SALMER, ABSTRACT Measured noise deviations over the video range 0-25 kHz off the carrier are presented for free running or injection locked Gunn oscillators and compared to those obtained with high order avalanche diode

PARTIALLY INTEGRATED ELECTRONICALLY OSCILLATORS TUNED MI LLiMETER-WAVE (33-75 GHz) GUNN John Ondria * ABSTRACT Experimental results are presented for varactor tuned GaAs Gunn-effect oscillators at millimeter-wave (33- 75 GHz) frequencies for both microstrip and suspended substrate configuration. An electronic tuning range of almost 2 GHz with an output power of +20 dBm :to.65 dB has been ach

INDIUM PHOSPHIDE TRANSFERRED ELECTRON DEVICES FOR MILLIMETRE WAVE APPLICATIONS I.G. Eddison, I. Davies and D.M. Brookbanks ABSTRACT Details are given of the current development stage of CW indium phosphide transferred electron oscillators (TEOs) designed for mm-wave applications. The aims of low-noise, good reliability and thermal stability dictate the use of n+-n-n+ epitaxial material, de

41 GHz 10 WATT SOLID STATE AMPLIFIER Dale W. Mooney and Franklin J. Bayuk ABSTRACT A solid state amplifier has been developed at 41 GHz and demonstrates 10 watts of CWoutput power. A two stage design using silicon double drift IMPATT diodes operating in the injection locked mode exhibits an operational bandwidth of 250 MHz with an associated gain of 32 dB.
