Abstract
Phase resonances are observed in the microwave response of metal transmission gratings comprised of identical but alternately orientated tapered slits. Despite each slit having identical dimensions, and being equally spaced from its neighbors, these high-Q mode are nonetheless supported even at normal incidence. The excitation of these ...
Phase resonances are observed in the microwave response of metal transmission gratings comprised of identical but alternately orientated tapered slits. Despite each slit having identical dimensions, and being equally spaced from its neighbors, these high-Q mode are nonetheless supported even at normal incidence. The excitation of these modes is attributed to the interference between Fabry–Perot-like modes and diffractively coupled surface waves.
