Abstract
Explicit formulas are derived for waves modeled by the scalar two-dimension al Helmholtz equation for the field that is diffracted when surface creepin g rays encounter an infinitely sharp edge. Both Neumann and Dirichlet bound ary conditions are analyzed, and the diffracted field is found to be an ord er to magnitude smaller in the latter case. (C) 2000 Acoustical Society of America.
