Abstract

The mode transformation effect is considered for axially tuned corrugated waveguides. Recently, this effect for transmitted fields was introduced by using a certain kind of material which couples the propagating fields. In this paper, a reflector type mode converter based on ferrite material is proposed. The properties of ferrite can be changed by using a static magnetic field, which allows the possibility for tuning to obtain an optimal mode transformation in reflection. The properties of transverse fields in reflection are considered.
