Paperback. Zustand: New. Print on Demand. This book presents an asymptotic expansion for two-dimensional outwardly radiating fields, expressed in terms of inverse powers of the distance from a point in a fixed region to a point in a circular neighborhood at a large distance. The author develops this expansion from an integral representation of these fields using saddle point integration. The coefficients in the expansion are linear combinations of plane waves and derivatives of plane waves with respect to angle of incidence. The expansion finds application in scattering problems by reducing scattering of arbitrary two-dimensional fields to scattering of plane waves, which simplifies the analysis and solution of these problems.
