Modeling of dielectric gratings to control the redistribution of energy in the spectrum of the scattered microwave optical and electromagnetic fields

The choice of the periodic structures based on hollow dielectric rods with filling, which offer the possibility to vary the dielectric constant is considered. The simulation results obtained for scattering of microwave and optical ranges electromagnetic radiation in equidistant structures based on dielectric rods with variable electrophysical parameters are given. The effect of variations in the dielectric constant of the structural components on the energy redistribution of harmonics of the scattered electromagnetic radiation is demonstrated.
