Abstract

The article is devoted to consideration of various variants of the solution of some problems of diffraction for printed arrays with anisotropic inhomogeneities. First of all spatial polarizing filters and a twist-reflectors based on microstrip reflectarrays are considered. If microstrip elements of a twist-reflector contain controllable loads, then qualitatively new type of the microwave device is formed. This device enables to control polarization of the scattered field. Such devices can be named by polarizing modulators or manipulators. By means of printed reflectarrays with elements of complex topology the spatial polarizers, which can transform electromagnetic waves with linear polarization in waves with rotating polarization and, in particular, in waves with circular polarization, are realized.
