Resonant cell with open entrance on the base of dielectric plate on a metal substrate

Possibility of converting the energy an incident electromagnetic wave to a surface in dielectric plate on metal substrate has been confirmed through numerical simulation. To transfer between waves different structures, diffraction grating placed is used. Energy retained formation resonator by introducing aflush walls along plate’s ends. Thus, resonant cell with open entrance suggested – enters whole lit plate. It assumed that small losses, and its consists identical bars, which are made same have cross section. The resonance form sharp increase standing amplitude inside plate, compared amplitude, correspondingly wave’s absorption takes place at some periods. external manifestation decrease specular scattering from plate: observed RCS ray reflection direction was several times more than three orders magnitude under conditions. Stability solution problem follows smooth variation condition number vicinity even deepest reduction. Efficiency generation gratings types or arranging other periodical inhomogeneities within volume can be according depth resonance.
