Time-Domain Electromagnetic Scattering by a Two-Dimensional Narrow Groove—A Solution Based on the Cagniard–DeHoop Method of Moments

The pulsed electromagnetic scattering by a relatively narrow groove in a perfectly electrically conducting plane is analyzed using the Caginard–DeHoop method of moments. Semianalytical solutions are provided for the
$H$
-polarized EM fields in the presence of rectangular and V-shaped grooves. Illustrative numerical examples validate the solution methodology.
