Mode transformer for hard-surface waveguides [PDF]
31st European Microwave Conference, 2001, 2001 Mode transformation effect inside a corrugated circular waveguide filled with gyrotropic material, e.g., magnetoplasma or ferrite, is considered. The corrugation is in axial direction and the depth of the corrugation is a quarter wave length forming a boundary condition equal to a hard surface (HS).
