Abstract :
Two new nonreciprocal waveguiding structures - a grounded-dielectric/semiconductor slab and a grounded-semiconductor/dielectric slab have been investigated analytically and numerically. The results demonstrate nonreciprocal behavior and the potential for the design of phase shifters and isolators in millimetric and submillimetric wavelengths region. Dispersion diagrams are plotted to show the wave behavior for both structures.
