VARIABLE POLARIZER
Abstract
The objective of this work is the study and experimental verification leading to the design of a high power S-band variable polarizer. This polarizer is to transform the TE(10) mode to vertical linear, clockwise circular, counterclockwise circular, and horizontal linear polarizations. Switching time between degrees of polarization is to be 200 microseconds or less. The characteristics of the variable polarizer include the objectives of 1 mw peak, 2 kw average power operating over the band, 3.1 MHz to 3.6 MHz with the study including the feasibility to increase power handling to 10 mw peak, 20 kw average. Recent results indicate the feasibility of attaining the design goals by the use of nonreciprocal waveguide latching phasers as the active elements of the polarizer. Polarizer power levels to 920 kw peak and 3600 watts average (depending upon polarizer configuration) have been attained, the present limit being the testing facilities available. Studies have included various polarizer configurations which appear compatible with system concepts and the development in individual phaser elements necessary to meet polarizer requirements.
