Abstract :
This letter describes a cell-centered finite-volume time-domain method for solving electromagnetic problems which involve media having finite conductivity. Two different approaches, the additive induced source technique and the fractional-step technique (FST), are considered and compared with a reliable numerical method. Namely, the former treats the induced electric current density as an additive source term, whereas the latter is based on the FST.
