摘要：

A new method of solving the reflection diffraction problem using a stabilized edge in a multislice-type calculation is described. Results that compare it with Bloch-wave calculations show that it is a very robust solution and for one surface raises an important issue concerning the boundary match in the Bloch-wave approach. It is shown that the standard boundary match used is often invalid for reflection problems and may also be questionable for transmission problems although here the effects will be smaller. The correct boundary match on a surface which need not be flat is described.
