The computation methods of electromagnetism parameters, electromagnetic wavefrequency and medium slice thickness in microwave measuring for composite material were analyzed.
分析了复合材料微波检测中电磁参量、电磁波频率和介质薄片厚度的计算方法。
2
In dynamic state all the medium parameters are complex functions verse frequency, and wave expression is also a complex function verse frequency.
在动态情形下所有的介质参数都是依赖于频率的复函数，波也用频率的复函数表示。
3
It will give patients treatment by means of the amplified amplitude modulating wave current that can be obtained form mediumfrequency amplitude modulated by the low frequency pulse signal.
