The singularity expansion method SEM is applied numerically to the electromagnetic dual of the rectangular aperture in a screen of infinite extent--the rectangular plate in free space. The SEM quantities are determined through a numerical treatment of the applicable electric field integral equations, and the details relating to computational efficiency are described. The pole trajectories for the plate are given for a range of aspect ratios, along with natural modes at specimen poles. Physical and numerical interpretations for these data are stated where possible. Author
