An assessment of accuracy of approximate mathematical model of pulse electromagnetic field of current flowing near conductive body

摘要

An assessment of accuracy of asymptotic method for analysis of a three-dimensional pulse electromagnetic field created by arbitrary current contour, which is located near the flat surface of a conductive body, has been considered. Comparison of the exact and approximate values of integrand function for exponentially damped impulse has shown correspondence of theoretical estimations for asymptotic series' terms and calculation results.
