Research on the coupling of UWB pulse with water proof door of shielding room

The UWB pulse could couple with the door of a shielding room on ship and partly get through. The high power energy of the UWB (Ultra wade band) pulse would damage or even destroy the high sensitive equipments. So, this article analyzes the rules of this coupling with FDTD emulation method. Then carry out some radiation experimental to validate the simulation result. The result finds that the experimental result is consistent with the simulation result. Most of the UWB pulse energy can get through the door when the door is open at different state.
