In this paper, we show how Prolate Spheroidal Wave Functions (PSWFs) can be reliably and accurately numerically computed to represent the field radiated by an oblong antenna. We show the convenience of the PSWFs representation by comparing its performance against a spherical harmonics expansion. We also point out how the PSWFs representation can be fruitfully exploited to face a Near- Field/Far- Field (NFFF) problem in a cylindrical geometry for the mentioned class of antennas.

Abstract
In this paper, we show how Prolate Spheroidal Wave Functions (PSWFs) can be reliably and accurately numerically computed to represent the field radiated by an oblong antenna. We show the convenience of the PSWFs representation by comparing its performance against a spherical harmonics expansion. We also point out how the PSWFs representation can be fruitfully exploited to face a Near- Field/Far- Field (NFFF) problem in a cylindrical geometry for the mentioned class of antennas.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
