Abstract :
Back reflection from the end of a parallel-plate metal waveguide (PPWG) can be enhanced up to 99% at a selected frequency by patterning on the output facet. The enhanced reflectivity depends on the incident angle in the PPWG and shows a lateral shift comparing to mirror reflection, which is an analogue of the Goos-Hanchen effect in this context. We show how this concept can be used as the basis for designing resonant waveguide structures.
