A PROTOTYPE OSCILLATOR CIRCUIT UTILIZING EVANESCENT MODE RESONATORS by R. Knochel and K. SchUnemann ABSTRACT: A prototype oscillator circuit is described which uses evanescent mode resonators as housing for active devices. The circuit is applied to voltage controlled oscillators, injection locked oscillators as FM-amplifiers and frequency dividers, and cavity stabilized oscillators. Desig

BIOLOGICAL EFFECTS BY MICROWAVES Andre-Jean BERTEAUD and Michele DARDALHON ABSTRACT Domestic and industrial applications of microwaves are everyday extended implying protection conditions and safety standards which require a better knowledge of biological effects associated with microwave radiations. Interactions of microwaves with living systems are reviewed on the basis of levels of organi

STATUS AND TRENDS IN MICROWAVE ACOUSTIC DEVICE DEVELOPMENTS Kjell A. Ingebrigtsen* ABSTRACT The implementation of the surface acoustic wave technology has transferred microwave acoustic devices from "one of each kind" to a mass production oriented technology. This has provided a new class of devices which are cost competitive with alternative technology in a variety of applications. The prese
