The inversion problem in classical electrodynamics is investigated in great detail in connection with the "Casimir theorem" which states that given all multipoles (both electric and magnetic) of a given charge and current distribution localized in a finite region, the electromagnetic field outside t
Scanning spherical lens antennas are typically constructed using concentric dielectric shells with external primary feed. A cover layer may also be used. A modal expansion method is reported whereby the scattering matrix of this structure is derived and which accounts for both internal and external
## Abstract This paper demonstrates how the reflection error of a radiation pattern can be reduced by means of an optimised spherical wave expansion (SWE). Disturbed and undisturbed radiation patterns are measured with and without an aluminum mast near the measured antenna. The SWEs are calculated
