On asymptotics of a wave field near the origin of an interference head wave
Let an incident wave propagates in a medium with wave-speed c1 and illuminates a convex interface to a medium with propagation speed c2, c2 > c1 . Let at some point O an incident ray meets an interface under critical reflection angle, then such a point looks like a source of an interference head wave which propagates in the first medium along the interface with the speed c2. The wave field in a vicinity of O is rather complicated. In the paper, we discuss its high-frequency asymptotics.
