Abstract :
An integral equation solution is obtained by careful application of the moment method and the utilization of the symmetric property. The authors present guidelines that make it possible to avoid redundant computations of the impedance elements and that reduce the computation time as well as the memory space through dedicated matrix computation routines. Computed RCS patterns for a 90 degrees C corner reflector for both vertical and horizontal polarizations are shown and found to compare well with high-frequency predictions and experimental data.<>
