Abstract

The localization of the plane wave expansion is considered for the analysis of wave beam transformations on transversely inhomogeneous structures. To implement compact localization in the spatial domain, it is proposed to use a system of non-intersecting rectangular windows. Problems of discrete realization of local plane wave expansion are analyzed. An algorithm for the numerical implementation of the localization of the plane wave expansion based on the quasisolution search method is proposed. Its advantage over the algorithm based on the discrete Fourier transform is demonstrated. The efficiency of its use has been demonstrated by the example of analyzing the wave beam reflection from the secondary aperture with transverse inhomogeneity.
