Frequency selective surfaces - Spectral characterization and application to multifrequency antenna systems
Abstract
The spectral characterization of FSS (frequency selective surfaces, used as quasi-optical diplexers in reflector antenna systems for communication satellites) is considered, and the solution of the scattering problem by the moment method is described. The general characteristics of the FSS frequency response when the incident field is a plane wave are examined. Also presented is a method to analyze FSS behavior in the actual operating environment, with particular attention given to the near-field region of the feeds.
