Abstract :
A two-dimensional time-domain application of a general finite-element mathematical package, IMSL:PDE/PROTRAN, is considered for two-dimensional shielding problems. The software runs on the IBM 3090 mainframe computer. The shielding problem is formulated via the magnetic vector potential and the Coulomb gauge. Validation of the program is performed via a simple test problem (plane wave incident on a perfect conductor). Results are presented for the case of a plane wave with double exponential time dependence incident on the shield.<>
