电磁波在碳酸岩地区的传播特性研析

A STUDY OF PROPAGATION CHARACTERISTICS OF ELECTROMAGNETIC WAVE IN CARBONATE AREA

形成岩溶的高阻碳酸岩对电磁波的吸收较弱，而且碳酸岩成层沉积的特定环境使碳酸岩地区岩石的各向异性现象较明显，由于地空界面的存在及岩溶洞壁两侧介质电性差异明显，界面清晰，又使电磁波出现强烈的反射及散射现象。本文从理论上对碳酸岩地区电磁波传播的特有现象进行了研究和分析，并给出了结论。

High - resistance carbonate rocks that form karst merely show weak absorption of electromagnetic wave; basides; the specific layered deposition environment of carbonate rocks has caused fairly obvious anisotropic phenomena of rocks in carbonate rock areas. The existence of air - earth interface and the distinct interface caused by the obvious difference in electrical properties between media on both sides of the karst cave also lead to intense reflection and scattering of electromagnetic wave. The present paper made a study and analysis of the specific electromagnetic wave propagation phenomena in carbonate areas and; on such a basis; reached some conclusions.
