Well, 1 THz corresponds to about 0.3 mm wavelength, which is far thermal infrared. I expect some would be absorbed and some reflected, depending on the surface characteristics. I don't think even ordinary conductors are transparent to this frequency of radiation. It takes x-rays to penetrate a superconductor. Regards, Horace Heffner
