Abstract :
Electromagnetic scattering from an electrically small circular PEC disc is considered. The exact solution of the scattering problem given by Meixner and Andrejewski is used to derive the low frequency (Rayleigh) approximation for the scattered field. The results are compared with those obtained by expanding the fields on the disc in powers of k. Characteristic features of the low frequency scattering from the disc are studied, and closed-form approximations for various scattering cross sections are presented.
