The Design of Multi-bandpass FSS

This article describes the features of basic frequency selective surfaces technology (FSS), presents the basic principle and essential method for design of double band pass and tri-band pass FSS, and the great performance was achieved by emulation and test results. This type of FSS can be used for sub reflectors and radomes, and provides a good basis for the theory and methodology of the frequency reuse and reducing radar cross-section (RCS).
