| 摘 要： | 现代电磁法勘探中,总是遇到探测深度和分辨率的矛盾,两者难以兼顾.本文介绍的一种基于特殊函数的高频电磁波源,它在地质体中的衰减速度慢于常规简谐电磁波.以此种电磁波作为波源可以大大提高探测深度,同时也保证了高分辨率.本文通过计算比较两种电磁波的趋肤深度,发现基于特殊函数的电磁波的趋肤深度远大于一般的简谐波.

| Abstract: | When we use electrical method to explore, we are often faced with problems between depth and resolution. This article introduces a high frequent electromagnetic source based on a kind of special function. This kind of wave decays more slowly than normal ones in medium. So we can explore deeper place underground by using this electromagnetic source and keep high resolving power. This article compares the skin depths between these two kinds of waves,and find the skin depth of the wave based on a kind of special function is far longer than normal ones. |
