“…Although periodic structures such as diffraction gratings have a long history, their resonant behaviour in combination with composite media is rather novel and theoretically interesting as well as exciting for technological developments [5][6][7]. A rather novel study carried out in papers [8][9][10] has shown that the incident wave energy can be effectively absorbed in a resonant way by the structure consisting of a diffraction grating and absorbing medium with one of the constitutive parameters negative. For simplification the frequency dispersion of the constitutive parameters was not considered in those works.…”

Theoretical results on the plane electromagnetic wave diffraction from a structure as a strip periodic grating on a paramagnetic layer, the permeability of which possesses negative real part in the microwave band, are obtained using analytical regularization based on the solution to the Riemann-Hilbert problem. The effect of the resonant transmission accompanied by extremely high absorption is thoroughly studied across the frequency band of the surface waves of the paramagnetic layer placed in the biasing magnetic field. This effect is caused by the surface waves of the layer excited resonantly by the plane incident wave with the diffraction grating present. The resonant frequency is electronically tuned by the biasing magnetic field.

“…A considerable amount of research in the recent decades has been devoted to electromagnetic properties of such complex media as chiral materials, omega-medium, bi-anisotropic medium [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Serious efforts have been directed towards building microwave composites whose effective permittivity and permeability can take negative values [9,10,14].…”

“…A study of their electromagnetic properties has shown (see [17,18]) that in combination with various periodic structures they can absorb the incident electromagnetic wave energy in resonant way. This property can be used for creating novel devices, non-reflecting coatings and microwave antenna components.…”

Abstract-Theoretical results on the electromagnetic properties of such a structure as a negative-permittivity layer placed on a reflecting grating are discussed. Effect of this structure resonant absorption of the excitation electromagnetic energy is studied in a wide range of problem parameters. The sufficient conditions of the effect appearance are determined by solving the dielectric-layer eigenoscillation problem. A comparative analysis of the absorption by the negative-and the positive-permittivity structures is made to reveal the characteristic features of the effect. Phenomenon of the absorption resonance splitting is shown in the case of plane wave oblique incidence on the structure. The E-polarized plane wave diffraction is considered to find out essential difference of the resonant absorption in the E and H cases.
