High accuracy numerical simulation of large loop source electromagnetic field

摘要：

Large loop source be used in electromagnetic prospecting often,such as TEM, SNMR and so on.The accuracy of large loop source electromagnetic field directly influences physical model response calculation.In this paper,we make an experimentation that using chave algorithm in function contains bessel function numerical integration,contrast with analytical solution,we found that this algorithm using in function containing bessel function numerical integration is feasible.The result shows that this algorithm has a good astringency,high accuracy and a higher speed.This algorithm also be used in high accuracy numerical simulation of large loop source electromagnetic field,we discovered many distribution rules of large loop source electromagnetic field.
