Edge-Guided Mode Performance and Applications in Nonreciprocal Millimeter-Wave Gyroelectric Components

Abstrakt

The analogies between the behavior of gyromagnetic and gyroelectric nonreciprocal structures, the use of the simple transfer matrix approach, and the edge-guided (EG) wave property, supported in a parallel plate model for integrated magnetized semiconductor waveguide, are investigated in those frequency regions, where the effective permittivity is negative or positive. As with their ferrite counterparts, the leakage of the EG waves along the curvilinear semiconductor-metal edge is observed for those frequencies where the effective permittivity is positive. This induces spurious resonances in the semiconductor junctions having a convex–concave geometry. Furthermore, the very small reflection from the open semiconductor edge is observed for those frequencies where the effective permittivity is negative. This provides the unidirectional wave propagation in the parallel plate semiconductor (PPS) guide where one edge is open as well as in the PPS guide inserted into a dc magnetic antiparallel field. Hence, as a practical application, new EG mode nonreciprocal semiconductor devices are proposed as complementary to the already known ferrite versions. The simulated characteristics of the ideal junction and their implementation in finline technology clearly illustrate their broadband, nonreciprocal operation in the millimeter-wave regions (25–250 GHz), something which is difficult to achieve with ferrite devices
