Analysis of Stability and Dispersion in a Finite Element Method for Debye and Lorentz Dispersive Media

Creator:

Banks, H. T., Bokil, V. A., and Gibson, N. L.

Abstract:

We study the stability properties of, and the phase error present in, a finite element scheme for Maxwell’s equations coupled with a Debye or Lorentz polarization model. In one dimension we consider a second order formulation for the electric field with an ordinary differential equation for the electric polarization added...

Dispersion reducing methods for edge discretizations of the electric vector wave equation

Creator:

Bokil, V. A., Gibson, N. L., Gyrya, V., and McGregor, D. A.

Abstract:

We present a novel strategy for minimizing the numerical dispersion error in edge discretizations of the time-domain electric vector wave equation on square meshes based on the mimetic finite difference (MFD) method. We compare this strategy, called M-adaptation, to two other discretizations, also based on square meshes. One is the...
