图5 利用矢量网络分析仪(Agilent N5234A)测得的谐振器空载及加载样品调谐前后的S11参数曲线,图中插图为加载粉末样品的谐振器正反面的实物照片.经过铜箔调谐后,谐振点的微波反射是调谐前的一半
Fig. 5 S11 parameter diagram of the resonator without samples and with samples before and after tuning that is measured by vector network analyzer (VNA, Agilent N5234A); the illustration in the figure is the resonator loaded with powder sample. The microwave reflection at the resonance point is halved after tuning with copper flake
