Abstract
In designing and verifying a millimetre/submillimetre wave radiometer a computational tool is required to evaluate the passage of a signal beam through an optical network as a sequence of field transformations at successive focusing reflectors and planar FSSs. This paper discusses how the passage of a beam through a planar optical component can be analysed using the angular-spectrum-of-plane-waves representation of the signal beam. The planar components are plane metallic grids or gratings, or dielectric plates, in interferometric combinations to provide wide-band demultiplexing, side-band separation, or isolation. The beam's angular spectrum is made explicit in a computation of its far field.
