Rapid calculation of paraxial wave propagation for cylindrically symmetric optics.
When calculating the focusing properties of cylindrically symmetric focusing optics, numerical wave propagation calculations can be carried out using the quasi-discrete Hankel transform (QDHT). We describe here an implementation of the QDHT where a partial transform matrix can be stored to speed up repeated wave propagations over specified distances, with reduced computational memory requiremen...
متن کاملComplex Wavenumber Rossby Wave Ray Tracing
This paper presents a methodology for performing complex wavenumber ray tracing in which both wave trajectory and amplitude are calculated. This ray-tracing framework is first derived using a scaling in which the imaginary wavenumber component is assumed to be much smaller than the real wavenumber component. The approach, based on perturbation methods, is strictly valid when this scaling condit...

متن کاملRay-tracing Method for Estimating Radio Propagation Using Genetic Algorithm
We propose a GA ray-tracing method which applies a genetic algorithm to ray tracing in order to complete the large-scale computation of estimating radio propagation in a practical amount of time. We describe the GA ray-tracing method as well as a demonstration of its effectiveness through numerical simulation .
متن کاملRadio-wave propagation prediction using ray-tracing techniques on a network of workstations (NOW)
Ray-tracing based radio wave propagation prediction models play an important role in the design of contemporary wireless networks as they may now take into account diverse physical phenomena including reflections, diffractions, and diffuse scattering. However, such models are computationally expensive even for moderately complex geographic environments. In this paper, we propose a computational...
