A comparative study of numerical algorithms for computational electromagnetics
Characteristic-based finite-difference and finite-volume schemes have been developed for solving the three-dimensional Maxwell equations in the time domain. Although the basic concept of the two algorithms is identical, the detailed formulation is vastly different for achieving split fluxes according to the sign of the eigenvalues. A comparative study of these algorithms applied to an oscillating electric dipole is carried out to determine the most efficient numerical procedure for future applications. On spherical coordinates, second-order windward numerical simulations of the radiating phenomenon are closely comparable in terms of accuracy and efficiency. These methods also demonstrate an ability to suppress reflected waves from the truncated boundary. The third-order upwind biased finite-volume scheme reveals a superior performance in stability properties and higher numerical accuracy. © 25th AIAA Plasmadynamics and Lasers Conference.
