A combined equivalent source and geometric optics approach to analysis of radome

In this paper, a hybrid method is present based on equivalent surface aperture integration(ESAI) and geometry optics(GO). In this algorithm, the reflected field along the inner surface of radome is approximately regarded as equivalent currents, which radiate through the wall and constitute the total field together with the transferred field. The integration over the out surface generates exact far field. The theoretical simulation agrees with the measurement quite well.
