Phase resonances in obliquely illuminated compound gratings

Mostrar todas las versiones(2)

The existence of phase resonances in obliquely illuminated, perfectly conducting compound gratings is investigated. The diffraction problem of a p-polarized plane wave impinging on the structure is solved using the modal approach. The results show that even under oblique illumination, where no symme...
