Efficient and accurate modeling of electrically large dielectric lens antennas using full-wave analysis

Two efficient analysis methods for the accurate modeling of electrically large dielectric lens antennas are presented. The first method is based on Double Physical Optics (PO), which takes into account an additional set of reflections within the lens, whereas the conventional PO method only accounts for one set. The second method relies on a higher-order Body of Revolution Method of Moments and is capable of providing a full-wave solution of a 100-wavelength dielectric lens antenna within 2 minutes on a laptop computer.
