Abstract
We have measured the complex index of refraction of Ba(Mg1/3Ta2/3)O-3 bulk material using coherent THz time domain spectroscopy. The transmission spec trum of Ba(Mg1/3Ta2/3) in the 0.1-1.0 THz region is obtained. The real part of the index of refraction of Ba(Mg1/3Ta2/3) in this band is estimated (si milar to4.87), and is comparable with the dielectric constant measured at m icrowave frequency. The measured Q-factor is around Q . f = 40 THz, which i s slightly smaller than the Q. f-values of the Ba(Mg1/2Ta2/3)O-3 materials in the microwave regime (Q . f = 60, 000 GHz in 10 GHz).
