Metaplectic Geometrical Optics

Nicolas A. Lopez

Ray optics is an intuitive and computationally efficient model for wave propagation through nonuniform media. However, the underlying geometrical-optics (GO) approximation of ray o…

Metaplectic geometrical optics for modeling caustics in uniform and nonuniform media

N. A. Lopez, I. Y. Dodin

As an approximate theory that is highly regarded for its computational efficiency, geometrical optics (GO) is widely used for modeling waves in various areas of physics. However, G…

Restoring geometrical optics near caustics using sequenced metaplectic transforms

N. A. Lopez, I. Y. Dodin

Geometrical optics (GO) is often used to model wave propagation in weakly inhomogeneous media and quantum-particle motion in the semiclassical limit. However, GO predicts spurious…
