Exposure Assessment Using the Dual-Grid Finite-Difference Time-Domain Method

Abstract

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. FDTD (DG-FDTD) simulation. The DG-FDTD approach has the significant advantages to remain stable along the computation and to be easy to implement in a typical FDTD code. When compared with classical FDTD analysis, the DG-FDTD approach exhibits a reduction in computation time and memory requirements by a factor of 2.3 and 3.2, respectively, while providing accurate results both in near-field and far-field radiation.

On the comparison between multiple‐region and dual‐grid finite‐difference time‐domain methods for the analysis of antenna arrays

“…In fact, it simply modifies the direction of the total field/scattered field decomposition and the position of the excitation surface, which is also easier to implement. With such a decomposition, different materials can go through the near‐field and excitation surfaces [9]. Moreover, this method is not limited to structures with an infinite ground‐plane.…”
