A Finite Element Perspective in Analyzing Maxwell 's Equations
Abstract
An analysis of the three-dimensional (3-D) finite element formulation of Maxwell's equations governing classical electromagnetic propagation in dielectrics is given including its analogy to Navier's equation. The weak form of the electric field equation is reviewed along with dispersion analysis and approximation equations. Radiation boundary conditions are also explored to include paraxial absorkr, Sandler absorber, and other absorkr comparisons. In addition, time domains vs. frequency domains are investigated with a listing of possible advantages and disadvantages. It was concluded that if large-scale calculations need to be done today, the-domain techniques provide the most practicable means; however, it is still premature to promote such solvers as production level tools for engineers.
