Abstract
An expression is derived for the spatially dependent Green function or response function in a solid occupying a half-space and having generally varying properties. The expression is valid in the same range as the WKB approximation, namely for slowly varying properties. Some generalisation is indicated and the time-dependent Green function or the resolvent is obtained as a Fourier transform.
