摘要
当电子自旋共振发生在微波段时,根据微波段电子自旋共振条件,并使用电子顺磁共振谱仪和微波元件(波导管、谐振腔、短路活塞、环行器)等实验仪器测量出微波的波导波长,可以计算出真空中微波的波长.利用特斯拉计测量出共振时的磁感应强度,从而计算出了电磁波的传播速度.
When electron spin resonance occurred in the microwave band, the wavelength of the microwave in waveguide was measured using electron paramagnetic resonance spectroscopy and microwave components （waveguide, cavity, short piston, and circulator） according to the condition of microwave band electron spin resonance. The vacuum wavelength of the microwave was calculated. The magnetic induction was measured using Tesla meter, thus the velocity of electromagnetic wave was calculated.
