Abstract :
We have experimentally investigated the terahertz (THz) transmission properties of metalized-film attenuators (MFAs) with base film thicknesses of 6 μm and 25 μm. Transmittance of the MFAs was measured by a THz time-domain spectrometer. Good flatness and repeatability of the transmittance were verified for the 6 μm-thick MFA in the frequency range up to 3 THz.
