High Frequency Approximation of Integral Equations Modelizing Scattering Phenomena


    In this paper, we present a new way of discretizing integral equations coming from high frequency wave propagation. Indeed, using the eikonal equation, we will write that the solution is locally the product of an amplitude by an oscillating function whose phase gradient modu-lus is the wave number. Discretizing in order to keep this relation, we will show… (More)
