| Popis: | The enhancement of air-ground electromagneticmatching 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, amplifyingor nonlinear (Kerr-type) materials. Numerical results showthat a suitable chirped multilayer structure can reduce the re- ection from the ground. Different values of the number oflayers and of the layer thicknesses are considered. The distributions of the electric eld components and the power owdensity within the modelled structures are calculated. |
