Advancing of electromagnetic waves through nonlinear film in the microwave receiver antennas

Nonlinear boundary conditions were first used in Shifrin Y. S. et al. (2003). After that, the integral equation construction for research antennas became possible. Works on the propagation plane strong waves in the nonlinear half space were generalized in [Landau L. P. et al., (1982), p.531-534]. Boundary conditions for the dielectric and magnetic permeability have ε(E) and μ(H), were constructed. Thus, the decisive propagation task became relatively simple. The possibilities of utilization of these conditions are considered here for: a) different nonlinear types of film; b) arbitrary direction of incident wave.
