HIGH SELECTIVITY AND CONTROLLABILITY OF A PARALLEL-PLATE COMPONENT WITH A FILLED RECTANGULAR RIDGE

Achieving and controlling highly selective response in an electronic component could be particularly beneficial for numerous practical applications. In this work, we consider a simple configuration of a discontinuous parallel-plate waveguide with a narrow rectangular ridge filled with axially anisotropic material. The formulated boundary value problem is rigorously treated with help from mode matching technique. The variables with respect to which the device exhibits highly selective behavior and the parameters through which the regulation of sharp variations becomes possible, have been identified. Several graphs demonstrating these properties are analyzed and discussed.
