Babich's expansion and the fast Huygens sweeping method for the Helmholtz wave equation at high frequencies

In some applications, it is reasonable to assume that geodesics (rays) have a consistent orientation so that the Helmholtz equation can be viewed as an evolution equation in one of the spatial directions. With such applications in mind, starting from Babich's expansion, we develop a new high-or...
