QUASI-RESONANT ABSORPTION OF TE POLARIZED WAVES BY METAL-DIELECTRIC GRATINGS
This paper presents a numerical study of the quasi-resonant absorption of TE-polarized waves by a periodic structure of the metal-dielectric grating type on a dielectric substrate. The parameters of such a metal-dielectric grating, in particular the period, are chosen in such a way that no waveguide resonance occurs in the grating. The absence of resonance is evidenced by low fields at grating boundaries with homogeneous dielectric media.
