图7 两种不同基底材料及无基底时谐振器的S11曲线,图中插图(a)为Zerodur作基底时DPPH样品的ESR信号,插图(b)为Si作基底时样品的ESR信号.当谐振器加载Zerodur和Si时,谐振器谐振频率分别偏移到6.57 GHz和6.35 GHz.两次测试得到的g值分别为1.972 3和1.973 1,相对误差为0.041%
Fig. 7 (a) S11 curves of the resonator with two different substrate materials and without substrate, illustration (a) shows the measured ESR signal of DPPH covered with Zerodur, illustration (b) shows the measured ESR signal of DPPH covered with Si. The resonant frequency of the resonator changes to 6.57 GHz and 6.35 GHz while Zerodur and Si are loaded. The g values obtained from the two side tests are 1.972 3 and 1.973 1, respectively, with a relative error of 0.041%
