Evaluating the electromagnetic field is a fundamental aspect of electromagnetics and is crucial in various scientific and engineering disciplines. It involves determining the strength and direction of the electric and magnetic fields at different points in space and time. Finite Element Method (FEM) divides the problem domain into smaller elements and uses variational techniques to solve for the electromagnetic fields. FEM is particularly good for handling complex geometries and inhomogeneous materials.
