The fabrication method of hard template substrate supporting in the lithography process is proposed to realize THz devices based on low loss polymer substrate with large effective area. Based on this method, the THz polarizer with single layered and double layered grating structure are fabricated and measured. The transmission spectra indicates that the loss of the polarizer is low and the polarization extinction ratio is as high as 55dB and 70dB for single and double layered samples respectively. The THz band stop filter result indicates that the loss keeps low and the filter band width is wider for the multi-layered metallic structure.
