Here we present a new method for electromagnetic parameter measurement of low loss fiber,based on the classic “perturbation method” theory.
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。
In sinusoidal steady-state,if the terminal of lossless uniform transmission lines is open circuit or short circuit or reactance load,the voltage and current of the transmission lines are all standing waves.
在正弦稳态情况下,无损均匀传输线终端开路、短路或接纯电抗时,传输线上会出现驻波。
