The diffraction by a conducting wedge of a transient electromagnetic disturbance in the form of a plane wave discontinuity having arbitrary polarization and direction of propagation is reduced to a pair of two-dimensional scalar problems. The solution to one of these is identical with that previously obtained for the analogous acoustical problem, while the second is attacked in a similar manner, using a Tschplygin transformation to reduce the boundary value problem to one in potential theory, which is then solved by classical means.

In this paper, the electromagnetic pulse due to a delta-function current excitation has been derived on the planar surface of a perfect conductor coated by a dielectric layer. The approximate expression of wave component is obtained when both the transmitting source and the receiving antennas are located on the surface of the dielectric. When the thickness of the intermediate layer is subjected to the condition of k1l<<0.6, this physical model is applied to the microstrip circuit. Analysis and computations of the wave components are carried out on the microstrip circuit, including the surface trapped wave vector which had been ignored in former studies. It is shown that the trapped-surface-wave terms should have been taken into consideration as the main contribution in total transient field in the far-field radiations.

Exponential Pulse

Transient electromagnetic pulse (EMP) can easily couple into the inner of targets via apertures. To calculate the EMP coupling effects on a cylinder object with openings, the coupling course is simulated using sub-gridding FDTD algorithm in this paper. Gauss pulse and double exponential pulse are selected as the incident pulse source. The coupling EM field strength E inside the object and the current density J on the surface are calculated. Several rules about EMP coupling effects are gotten both in time and frequency domain. The results can help us to understand the damage effects of transient EMP.
