Abstract

The characteristic spectral response of an inclined strip grating, either free-standing or embedded in a dielectric slab, is quite sensitive to variations of the cant angle. It is an attractive frequency-selective surface which allows considerable design flexibility through the cant angle and/or the refractive index of the host dielectric. The inclined strip grating is analyzed through an indirect mode-matching technique based on Green´s second theorem. The analytical approach is simple and numerically efficient. Calculations focus on the effect of cant angle on the magnitude of all propagating Floquet harmonics on both sides of the structure. Interesting features of the scattering behavior are discussed
