- Publisher's Summary
- This book applies the method of moments (MoM) to compute the field scattered by scatterers as well as by an object above or below a random rough surface. Since the problem is considered as 2D, the integral equations are scalar and only the TE and TM polarizations are addressed. The book compares the MoM with the exact solution of the field scattered by a cylinder in free space and with the physical optics approximation for the scattering from a plate in free space. It then presents numerical results of the coherent and incoherent intensities scattered by different means. Coupling between the two scatterers is also examined.
