We propose a method to use an extension of the well-known FDTD algorithm on meshes that would typically imply severe time step size restrictions due to small geometrical details. For this purpose, the Newmark-Beta scheme, which is much less sensitive

We apply high-quality discretizations to simulate electromagnetic microwaves. Instead of the vector field presentations, we focus on differential forms and discretize the model in the spatial domain using the discrete exterior calculus. At the discre

We consider numerical determination of the dielectric media parameters of inclusions in a waveguide of rectangular cross-section from the transmission coefficient. We develop and apply computer codes implementing the FDTD algorithm for numerical solu
