Abstract
Approximate analytical results for the reflection amplitudes have been given in the long wave and short wave cases (Chapters 3 and 6). The long wave region of validity is extended by the perturbation and variational theories in Chapter 4, and the Rayleigh approximation of Chapter 5 is good at all wavelengths provided the reflection is weak. All these analytical methods share the drawback that higher-order approximations rapidly become cumbersome and thus of little practical value. For accurate results at intermediate wavelengths, and for a profile which is not among the few exactly soluble, numerical methods are needed.
