The application of DGTD in simulation of the open-ended cavity

The DGTD method is used to efficiently compute the radar cross section (RCS) of open-ended cavity problems. The perfect electric conductor (PEC) boundary conditions are given under the assumption that the thickness of the cavity wall is infinitely-thin. The comparison with the literature results shows that the method is effective. For the differences in the large incident angels, our results are evaluated using the MoM method.
