Beam focusing and consequences for Doppler Backscattering measurements
Juan Ruiz Ruiz, Felix I. Parra, Valerian H. Hall-Chen +5
The phenomenon of beam focusing of microwaves in a plasma near a turning-point caustic is discussed in the context of the analytical solution to the Gaussian beam-tracing equations…
New solution to Airy's equation for modeling beams near turning points
N. A. Lopez
Here I present a summarised description of the general behavior of waves near turning points. I show that when asymptotic matching to a prescribed incident wavefield is performed,…
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 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…
