Complex eigenfrequencies of axisymmetric perfectly conducting bodies - Radar spectroscopy
Abstract
The study investigates the changes of a body's complex eigenfrequencies as the shape is deformed from the perfectly symmetrical sphere to axisymmetrical prolate spheroids and finite, short right circular cylinders. The T-matrix permits a decoupling of the azimuth modes of the cross section axisymmetric conducting bodies. On the basis of an eigenfrequency secular equation it is shown that there is a splitting of the complex poles as a sphere is deformed into a spheroid or cylinder. A level scheme, like the energy-level diagram in optical spectroscopy, is thus possible.
