Highly Parallel Ray Based Wave Propagation Modeling and Improved Accuracy Concepts for Radiation and Scattering Problems Involving Composite Metallic and Dielectric Objects

Beschreibung

A powerful parallelized ray tracing algorithm, which can be employed for fast and accurate wave propagation and scattering computations for arbitrary metallic and dielectric media, is the core contribution of this work. Moreover, different modeling approaches to improve the accuracy and efficiency of field- and current-based asymptotic methods in computational electromagnetics are investigated. Transmitter and receiver models for reliable near-field representations by ray-based methods and an alternative approach for scattering computations by utilization of a novel full-wave method are presented.
