We discuss an approach to represent the electro-magnetic field radiated/scattered by oblong objects. The field representation exploits Vector Prolate Spheroidal Wave Functions (VPSWFs) which are computed by a stable and accurate numerical scheme and take into account the a priori information about the geometry of the radiator/scatterer. The presented numerical results highlight the satisfactory accuracy and the convenience of the approach against the classical representation by spherical harmonics.

Abstract
We discuss an approach to represent the electro-magnetic field radiated/scattered by oblong objects. The field representation exploits Vector Prolate Spheroidal Wave Functions (VPSWFs) which are computed by a stable and accurate numerical scheme and take into account the a priori information about the geometry of the radiator/scatterer. The presented numerical results highlight the satisfactory accuracy and the convenience of the approach against the classical representation by spherical harmonics.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
