Abstract：In order to predict the risk of exceeding electric field radiation emisson test standards during the product design stage，a fast simulation method of electric field radiation emision test based on multi-port network theoryis proposed.The standard test is defined asa multi-port network.To efficiently determine the coupling relationship between transmisson and reception，scattering parameters among ports are calculated. The simulation accuracy of the test environment is verified by measurement.Experimental results demonstrate that the proposed method achieves an average error of lessthan 2 dB and 6 dB for continuous wave and pulse excitation，respectively，which highlights its effectiveness.Compared with traditional simulation methods，the proposed method significantly enhances accuracyand eficiency.Therefore，this fast simulation method of electric field radiation emisson test based on multi-port network theory holds great practical significance in predicting and evaluating risks associated with exceeding equipment’s electric field radiation emisson test standards.
