| Summary: | Based on the spectrum distribution of typical broadband electromagnetic pulses, we constructed a dispersive electromagnetic model rat with fine tissue and organ structure and calculated the internal electric field distribution in rats irradiated by two broadband electromagnetic pulses. The results showed that the field strength in the irradiated rats was highly dependent on the distribution of tissues. Different waveforms produced different electric field distributions in the body. The width of the pulse that penetrated the body was greatly narrowed. Furthermore, the low-frequency energy of the pulse at 10 kHz~1 MHz was markedly reduced. The peak field strength of the important tissues and organs of the irradiated rats was approximately 1% of the spatial peak field strength. The data provide a theoretical quantitative basis for establishment of the dose-effect relationship of pulsed biological effects. The data will also serve as a reference for simulation calculation of the effect of broadband electromagnetic pulses in living organisms. |
