Abstract :
Complex natural resonances of an elliptic cylinder are determined numerically by contour integration of the determinant of the moment matrix obtained in a homogeneous solution of the electric field integral equation (EFIE). These resonances compare well with asymptotic estimates derived from radial eigenfunction expansion for scattering from cylinders.
