Abstract

Professors Zirath and Kildal’s groups at Chalmers have started a cooperation on developing a spatial quasioptical grid amplifier. Initially most work is done by guest researcher and Master students. The waveguide components are studied in Kildal’s group; whereas the active grid is being studied in cooperation between Zirath’s group and Dr Weikle’s group in Virginia. The present paper describes the initial study of the waveguide components; involving the development of a hard horn transition from a standard waveguide to a quadratic quasi-TEM hard waveguide.
