N2 - Here we present the design of multilayer interference metamaterials that provide high-performance, terahertz quasi-optical bandpass and cutoff filters made on their basis. The filters help us to implement antialias filtering and subsampling (undersampling) methods in the terahertz time-domain spectroscopy (THz-TDS) technique. It is shown that the proposed approaches can significantly reduce the data acquisition time of the spectrometer, which in turn can speed up terahertz vision systems built on the basis of THz-TDS.
