Abstract :
In this paper we describe the development of an electromagnetic modelling technique to investigate edge illumination effects on finite size FSS performance. The work extends the commonly used unit cell approach and models the FSS as a linear array with Gaussian beam excitation. Bistatic scattering from the FSS is calculated at 23.8 GHz for a 45 incident beam. The results presented relate the beam size, edge illumination and scattering performance.
