Abstract
A simple and efficacious modality of introducing causal excitations in CST Studio Suite® time-domain simulations is described. It makes use of (concatenations of) so-called discrete ports that are shown to accurately substitute Dirichlet boundary conditions and replicate dipole excitations. Numerical experiments cogently demonstrate the approach's exceptional replication accuracy and computational effectiveness.
