A new kind of composite material was prepared by using stainless steel fibers to fill polyamide resin and columned shells were made with it.When electronical fuzes connected with electrical fire head were fit under the shell in the microwave anechoic chamber,experiments of damage effect of UWB electromagnetic pulse radiation with peak power of 1GW were conducted.The frequency band of pulse energy was mostly between 10MHz to 2GHz.When the distance between shell and antenna was more than 50cm,the fuze in the ...
