Abstract:

Fast equivalent cable bundle model is an approximate to traditional equivalent cable bundle method (ECBM), which the electromagnetic behavior of the cable bundle can be equivalent to only one cable if observed from a certain distance away. Compared with ECBM, cable grouping process is greatly simplified therefore could further save computation time and memory. In this paper, the effectiveness of fast equivalent method in full wave analysis is further investigated, and then the fast method is applied to vehicle cables to test its applicability using CST software. The influence of conductivity of ground plane and the height of irregular ground are considered according to real applications under high intensity electromagnetic pulse illumination. Finally the fast method is applied to typical locations of vehicle model and fairly good equivalent precision are achieved to show its practicability.

Key words: electromagnetic field and microwave technology, equivalent cable bundle method(ECBM), high intensity electromagnetic pulse, complex ground structure
