Lens Analysis Methods for Quasioptical Systems
The Method of Moments (MoM), Physical Optics (PO) and Geometrical Optics (GO) are compared for analysis of dielectric lenses. It is found that MoM can be used (with normal computers) for diameters of the lens up to 15ʎ, ʎ being the wavelength, whereas the approximate methods PO and GO must be used at higher frequencies. Good agreement between the different methods is found and efficient calculation of PO and GO is discussed.
