A study of the conditions of application of an approximate method for analysis of a three-dimensional pulse electromagnetic field with an arbitrary current loop, which is located near the flat surface of a conductive body, has been performed. It has been shown that each term of the asymtotic series is calculated with some accuracy, and therefore it has its own minimum cutoff frequency. An assessment of cutoff frequencies has been done and appropriate intervals from the pulse start have been obtained depending on the number of the series’ term and its chosen tolerable error.
