Regarding the extension of metaplectic geometrical optics to modelling evanescent waves in ray-tracing codes
N. A. Lopez, R. Højlund, M. G. Senstius
Metaplectic geometrical optics (MGO) is a recently developed ray-tracing framework to accurately compute the wavefield behavior near a caustic (turning point or focal point), where…
