Since additional systems have been added, with the intent to, for instance, encourage co-production or to attract filming and post-production work to assorted places – and always coming with various provisions attached – one may sp

The fundamental limits of the gain and efficiency of an antenna are explored. The antenna is confined in a sphere and all of the currents are assumed to run in a material with a conductivity that is a function of the radial coordinate. The analysis is based on the expansion of the electromagnetic fields in terms of vector spherical harmonics. Explicit expressions for the limits of gain and efficie
