| Abstract: | On the basis of transmission/reflection method for measuring electromagnetic parameters, the limita-tion of the traditional transmission/reflection method in the calculation of the dielectric microwave electromagnetic pa-rameters was analyzed. The electromagnetic parameters of air, the polyethylene wax and BaM-type ferrite were meas-ured by using time domain gating technology. The results show that time domain gating technology can significantly improve the precision and the stability of measurement for materials. |
