Abstract

Investigation on time-domain responses of the monopole in the presence of an in intentional electromagnetic pulses (EMP) is carried out in this conference paper. An efficient hybrid numerical method based on FDTD method combined with the thin-wire model using subcellular extension is implanted for studying an EMP coupling with some typical monopole antennas widely used in the communication systems. Our developed program code is used to capture the responses of the monopole antenna. The transient response characteristics of the antenna illuminated by different incident EMPs are shown and compared in detail. These results are useful for further evaluating electromagnetic environment and electromagnetic protection of some complex communication.
