Abstract: A superconducting cavity has a long time constant when the coupling factor of its output port is low so as to accumulate input microwave energy therein, and after a certain accumulation of the input microwave, an output microwave pulse with a large power is extracted from the cavity by suddenly increasing the coupling factor of its output port.
Abstract: A microwave gas discharge apparatus for use as a limiter or TR device or the like and employing a primary discharge arrangement which has a single resonator used for priming the discharge device and determining the priming energy frequency.

Abstract: A method and device for absorbing microwave energy avoid the expense and bulk of prior art arrangements, and provide greater efficiency, by forming a flame in the path of the microwave and supplying a seeding substance into the flame to produce a plasma flame column which absorbs the microwave. The seeding substance is preferably an alkali salt solution, e.g. KNO.sub.3.

Abstract: A high power duplexer in the millimeter region includes a beam excited plasma switch in combination with colinear waveguide transmission lines. The beam passes through four sets of slots which are positioned in the four narrow adjoining walls of the colinear waveguide transmission lines. A quasi-anode is used to aid in turn-on of the plasma switch.
