The compression is based on a spherical harmonic representation of radiation patterns in conjunction with a radiating mode expression of the surface current. The method is applied to study near field effects and the far field of an antenna placed on a ship surface. Furthermore, the electromagnetic scattering of an electrically large plate is investigated. It is demonstrated, that the proposed technique leads to a significant memory saving, making multipole algorithms even more efficient without compromising the accuracy.en2119-027520122511LGEP-SUPELECCompression techniquesFast multipole algorithmsScattering EMCIngenieurwissenschaftenJournal Article10.7716/aem.v1i2.24Journal Article
