Axisymmetric Electromagnetic Wave Propagation Computation Using the Constrained Interpolation Profile Scheme With Large Time Steps

Conventional explicit time-domain methods used to solve Maxwell's equations are reliable and robust but conditionally stable often require the fulfillment of condition Courant-Friedrichs-Lewy (CFL) ≤ 1. While this is acceptable for many applications, in some instances, where solved alongside systems with slower propagation velocities, prove costly. This case nonrelativistic electromagnetic Particle-In-Cell that required study plasma thrusters. Several algorithms have been proposed retain a nearly formulation using large time steps achieve higher CFL values. Among these semi-Lagrangian constrained interpolation profile (CIP) method. ability method handle > 1 has demonstrated planar 2-D-3-D cases, not done 2-D cases cylindrical symmetry. In article, procedure presented compute wave domains symmetry CIP The scheme extended ≥ ghost node deal axis singularity wall boundary condition. results compared fields Hertzian dipole coaxial cable, they show good agreement.
