Titel:
Multi-Radiation Center Transmitter Models for Ray Tracing 
Abstract:
Concepts to improve transmitter models for electromagnetic ray tracing are investigated. The goal is to increase the accuracy of radiated field prediction in the near-field region of the radiator while the ray-based field representation is retained. Basic idea is to divide the radiating structure in smaller parts and treat them as subtransmitters, instead of using only one single transmitter, which is common practice. Not only antenna elements are considered, but also their surroundings, i.e., o...    »
