Abstract :
The computation of the complex eigenfrequencies of prolate spheroids with an obliquely incident plane wave is discussed. The approach applied for these solutions is the geometrical theory of diffraction (GTD). It derives the closure conditions for a creeping wave traveling along the quasi-helix and the second phase matching condition with an azimuthal round of a prolate spheroid. The resulting complex eigenfrequencies agree with those obtained from T-matrix calculation
