摘要
基于微扰原理,提出了一种测试低损耗纤维材料的新方法,研制了测试腔体和相应的测试夹具,对X波段的纤维样品进行了测试,并给出了误差。电磁参数的测试范围为:ε′=1.5~10.0,μ′=1.5~10.0,tanσ=1×10-4~8×10-3,tanθ=1×10-4~8×10-3.
Here we present a new method for electromagnetic parameter measurement of low loss fiber, based on the classic "perturbation method" theory. Thus by develop ing corresponding test cavity and test fixture, several kinds of fiber samples in X - band have been tested , and the error of the result is given. The range of the electromagnetic parameter that can be measured is: ε' = 1.5 - 10.0, μ'=1.5-10, tanσ=1×10^-4-8×10^-3, tanθ=1×10^-4-8×10^-3.
