A Student-accessible Graphical User Interface-based FDTD Algorithm for Visualization of Electromagnetic Fields

摘要

The topic of Maxwell's equations and applications is always an interesting, though challenging area for faculty and students. This paper outlines a fast and user-interactive MATLAB-based graphical user interface (GUI) software for electromagnetic field calculations using a finite difference time domain (FDTD) algorithm. The significant reduction in computation time is achieved through a vector-based MATLAB algorithm, and additionally, the GUI user interface facilitates the understanding and modeling of electromagnetic field effects. This paper is primarily directed at teachers and students involved in advanced electromagnetic and RF design studies at the graduate level, for example, courses in microwave engineering, power engineering and biomedical engineering. Typical electromagnetic simulation studies are presented in this paper to illustrate the efficacy and user-friendly nature of the software.
