Abstract

The time-domain spatial pulse response functions are largely applied for the analysis of transient fields in problems dealing with radiation (Harris,1981a), but the existing solutions are limited to the specific cases of boundary conditions when the radiating interface is assumed to be either rigid, free or soft. At the same time the problem of reflection is, in fact, generally not treated in the time-domain, except for the specific computations for the radiation coupling functions (Cassereau et Guyomar,1987).The problems of reflection of spherical waves from the planar interface is studied in ω-k domain by means of their decomposition into plane waves.
