FREQUENCY SELECTIVE SURFACES FOR SPACEBORNE MISSIONS

International Telemetering Conference Proceedings / October 13-15, 1981 / Bahia Hotel, San Diego, CaliforniaPeriodic arrays of metallic scatters have found widespread application in microwave antennas as frequency selective surfaces. The exact surface reflection and transmission characteristics depend on the length, width, and spacing of the metallic elements, and the dielectric constant and thickness of the supporting structure. The arrays are effectively filters when used in this application, and it would seem more efficient to specify the response with poles. The poles of each array are calculated using the Singularity Expansion Method (SEM). How the poles vary with changing geometrical parameters are calculated and plotted. The currents, and charges induced on the scatterers are treated using Floquet theory which is incorporated in a vector E-field integral equation. The SEM parameters are presented in the form of appropriate graphs and tables. In addition these data are compared with previously obtained data for multiple bodies and in particular with data used in the design of the frequency selective surface for the GALILEO space mission.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
