On the intensity of focused waves near turning points
N. A. Lopez, E. Kur, D. J. Strozzi
A wave near an isolated turning point is typically assumed to have an Airy function profile with respect to the separation distance. This description is incomplete, however, and is…
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 ray-based modeling of caustics: Theory and algorithms
N. A. Lopez, I. Y. Dodin
The optimization of radiofrequency-wave (RF) systems for fusion experiments is often performed using ray-tracing codes, which rely on the geometrical-optics (GO) approximation. How…
Steepest-descent algorithm for simulating plasma-wave caustics via metaplectic geometrical optics
Sean M. Donnelly, Nicolas A. Lopez, I. Y. Dodin
The design and optimization of radiofrequency-wave systems for fusion applications is often performed using ray-tracing codes, which rely on the geometrical-optics (GO) approximati…
Exactly unitary discrete representations of the metaplectic transform for linear-time algorithms
N. A. Lopez, I. Y. Dodin
The metaplectic transform (MT), a generalization of the Fourier transform sometimes called the linear canonical transform, is a tool used ubiquitously in modern optics, for example…
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…
