Semiclassical measure for the solution of the Helmholtz equation with an
unbounded source [PDF]
Julien RoyerWe study the high frequency limit for the dissipative Helmholtz equation when the source term concentrates on a submanifold of R^n. We prove that the solution has a unique semi-classical measure, which is precisely described in terms of the classical properties of the problem. This result is already known when the micro-support of the source is bounded, we now consider the general case.View original: http://arxiv.org/abs/1302.0811
