摘　　要：本文主要介绍一种吸波材料的开场测试技术——表面感应电流的测量方法,即通过测量金属目标及其涂敷吸波材料后的表面电流分布以确定吸波材料的吸波性能。本文以圆柱目标为例介绍了有关的实验系统,并给出了k_a=15时金属圆柱及其涂敷吸波材料后表面感应电流的测量值和计算值,两值比较吻合。该测量方法特别适用于表面波吸波材料的研究。An open field method for measuring the property of microwave absorbing material was described.The property of microwave absorbing material can be obtained by measuring surface current distributions over conducting and coated tarkgets.A measurment system for measuring surface current distribution over a cylinder was introduced,the measured and calculated surface current distributions over conducting and coated cylinders were given at k_a=15;they are in good agreement.This method is useful to surface wave absorbing material study.
