摘要
通过对DHMS-1微波光学综合实验仪不同分光板与接收器之间驻波比的测量,定性地讨论了不同材料对电磁波反射的影响,并利用两者之间的行驻波简便地测量了电磁波的自由空间波长,与实际值相比基本吻合.
Based on the measurement results of standing wave ratio between light splitter and receiver on the DHMS-1 microwave spectrometer, the influence of different material on the reflection of electromagnetic wave are discussed. Moreover, the wavelength of electromagnetic wave are easily obtained by using the travelling-standing wave, the results are in accordance with the actual value.
