BjGmer, A. and J. Karlander, Invertibility of the base Radon transform of a matroid, Discrete Mathematics 108 (1992) 139-147. Let M be a matroid of rank r on n elements and let F be a field. Assume that either char F = 0 or char F > r. It is shown that the point-base incidence matrix of M has rank

## Abstract Physical optics (PO) is a wellβknown asymptotic technique for evaluating the fields scattered from an object. Evaluation of a surface integral forms the crux of this technique. In this paper, the PO integral is formulated for planeβwave incidence and farβfield observation. Then, this in
