Abstract :
Positions in the complex frequency plane of the poles in the electromagnetic scattering amplitude are presented for perfectly conducting prolate spheroids and finite-length cylinders with length-to-diameter ratios of up to 5.0. A modification of the Waterman T-matrix method has been used to obtain these poles for both classes of electromagnetic eigenvibrations of the scatterer and for various values of the azimuthal mode number.<>
