Multimode Analysis of Bragg Reflectors for Cyclotron Maser Applications

Abstract : Bragg reflectors are studied for application to mm-wave CARM oscillator resonators. The effects of mode coupling into undesired stray modes on reflectivity is investigated. A set of general equations for the coupled modes of rippled-wall resonators is derived. These equations can be solved using matrix-algebra techniques The method of this paper is then applied to two cases, a TE11, 85 GHz Bragg resonator and a TE61, 100 GHz Bragg resonator.
