Abstract

The enhancement of air-ground electromagnetic matching by means of a chirped multilayer structure is inves- tigated. The modeling and simulation of the considered struc- ture are performed by using the method of single expression (MSE), which is a convenient and accurate tool for wavelength- scale simulations of multilayers comprising lossy, amplifying or nonlinear (Kerr-type) materials. Numerical results show that a suitable chirped multilayer structure can reduce the re- flection from the ground. Different values of the number of layers and of the layer thicknesses are considered. The dis- tributions of the electric field components and the power flow density within the modelled structures are calculated.
