摘要：

This paper presents an Eulerian numerical method for the computation of a bi-valued solution of Hamilton-Jacobi type equation in a particular geometric setting. More precisely we consider high frequency electromagnetic fields in the vicinity of fold caustics. (C) 2003 Elsevier Science B.V. All rights reserved.
