Calculation about high-frequency electromagnetic response and cases analyzing

ZHENG Sheng-tan,ZENG Zhao-fa,ZHANG Dai-guo,WANG Zhe-jiang,YAO Jian(College of Geoexploration Science and Technology,Jilin University,Changchun 130026,China)  
Linear filtering algorithm with high density sampling is presented according to the low precision or low efficiency of the high-frequency electromagnetic responses of calculation.The algorithm is compared to other algorithms in precision and efficiency with the half-spaced media model,and the results shows that the algorithm presented here is more accurate and efficiency.The numerical precision of this algorithm in different parameters and transmitter-receiver offsets are also calculated and compared which will be very important in application.In additional,the second integral expressions of electromagnetic responses of layer model with horizontal loop source are deduced while the transmitter is set on the earth surface,so the divergence of numerical calculation is improved.
