Phase resonances in compound metallic gratings

We study the phase resonances in metallic compound gratings. The diffraction problem is solved by means of the modal method and the surface impedance boundary condition. The response of gratings made of various metals is analysed. Curves of specular efficiency, field amplitude and phase inside the g...
