Conversions Between Field Representations

We can convert an AntennaRepresentation into an AntennaRepresentation of a different type by the changerepresentation(Tnew::Type{<:AntennaFieldRepresentation}, aut_field::AntennaFieldRepresentation; kwargs...) command.

Refer to the following table to check if a certain original representation can be converted into a specific target representation by AntennaFieldRepresentations:

Original Representation			Target Representation
		`SphericalWaveExpansion{Radiated}`	`SphericalWaveExpansion{Incident}`	`SphericalWaveExpansion{Absorbed}`	`PlaneWaveExpansion{Radiated}`	`PlaneWaveExpansion{Incident}`	`PlaneWaveExpansion{Absorbed}`	`MLFMMSource`
`DipoleArray{Radiated}`		✅	✅		✅	✅		✅
`DipoleArray{Incident}`			✅			✅
`DipoleArray{Absorbed}`				✅			✅
`SurfaceCurrentDensity{Radiated}`		✅	✅		✅	✅		✅
`SurfaceCurrentDensity{Incident}`			✅			✅
`SurfaceCurrentDensity{Absorbed}`				✅			✅
`SphericalWaveExpansion{Radiated}`		✅	💨^[1]		✅	💨^[1]
`SphericalWaveExpansion{Incident}`			✅			✅
`SphericalWaveExpansion{Absorbed}`				✅			✅
`SphericalWaveExpansion{Radiated}`		✅	💨^[1]		✅	💨^[1]
`SphericalWaveExpansion{Incident}`			✅			✅
`SphericalWaveExpansion{Absorbed}`				✅			✅

ChangeRepresentationMaps

1Cannot be converted into the target representation in the same coordinate system. The coordinate system of the target representation must be translated with repsect to the origina coordinate system. The [transfer] method accomplishes this task.
