PlaneWaveSphericalTransmitMaps

The PlaneWaveSphericalTransmitMap type calculates the transmission between a PlaneWaveExpansion and a SphericalFieldSampling. It is implemented as a concatination of a PlaneWaveToSphericalMap and a SphericalTransmitMap, i.e., the PlanewaveExpansion is converted into a SphericalWaveExpansion and the transmission is executed as a SphericalTransmitMap.

The keyword arguments for the construction of a PlaneWaveSphericalTransmitMap are described in the following table

Keyword Argument	Short Description
`firstorder::Bool`	If true, spherical coefficients of the incident probe field are treated as `FirstOrderSphericalCoefficients`. A change from `false` to `true` drops all entries which correspond to non-first-order modes. A change from `true` to `false` replaces non-first-order modes by zeros.
`samplingstrategy::SphereSamplingStrategy`	Replace the `SphereSamplingStrategy`. This effectively creates a new instance of `SphericalTransmitMap` from scratch.
`incidentcoefficients::AbstractVector`	Replace the spherical coefficients of the incident probe field by the entries of the input vector. If the `SphericalTransmitMap` is `firstorder`, all entries of the input vector which correspond to non-first-order modes are ignored.
