摘要：

A quasi-optical and wide-angle (of inidence) polarization rotator is described and analyzed. It consists of three or more parallel, equispaced, wire-grid polarizers whose wires are oriented in different directions. With the proper choice of the number of grids, their spacings, and their relative orientations, such a polarization rotator is capable of operating over a broad frequency band and a wide range of angles of incidence. A seven-grid 90 degree polarization rotator was designed to operate over a 42 percent relative bandwidth for a plus or minus 60 degree range of angles of incidence with less than 0. 1 db transmission loss. Various designs based upon the authors' analysis are given.
