Modeling arbitrarily directed slots that are narrow both in width and depth with regard to the FDTD spatial cell
The hybrid thin-slot algorithm (HTSA) integrates a transient integral-equation solution for an aperture in an infinite plane into a finite-difference time-domain (FDTD) code. A general implementation for arbitrary thin slots is described. The 3-D FDTD code TSAR was selected for the implementation. The implementation of the HTSA into TSAR is based on a slot data file that includes the cell indices where the desired slots are to exist within the FDTD mesh. For an HTSA-defined slot, the wall region local to the slot is shorted, and, therefore, to change the slot's topology simply requires altering the file to include the desired cells. Results are presented for a rectangular hatch-type aperture coupling into a rectangular cavity.<>
