A study was conducted to analyze nonreflection nonlinear transmission of an electromagnetic wave through the region of an inhomogeneous plasma nonlinear wave barrier. The mathematical model used to analyze transillumination of a barrier during the interaction of a wave with the inhomogeneous medium was based on solving the Helmholtz equation, with cubic nonlinearity. It was found that other versions of nonreflection nonlinear transillumination of inhomogeneous wave barriers in the layered inhomogeneous plasmas were also possible in other media. The effect was possible for quasi-periodic inhomogeinities, with a number of layers. The results show that nonreflection transillumination and transmission of barriers is also possible for other types of waves in an inhomogeneous plasma.
