OpenSEMBA/DGTD: An Open-Source Full-Wave Maxwell’s Equations Solver

Abstract

Numerical solvers have been essential tools in the industry, R&D and other similar fields in the last two decades. While it is important to understand the advantages and limitations of most common methods and look for the best candidates in terms of simplicity, accuracy, and computational performance; the capacity to be able to simulate, with relative simplicity, complex physical problems and obtain results which can serve as validations or preliminary testing has increased efforts towards obtaining more efficient and stable methods. In this work, we will discuss our choice to utilize the discontinuous Galerkin in the time domain (DGTD) method by extending an available finite element method library, MFEM, which allows us to introduce a Maxwell's equations solver in all dimensions without having to implement the basic framework a numerical method would require. A basic form of a DGTD solver has been successfully implemented, with further development planned in the future.
