Abstract :
In this paper, a dual-resonance bandpass THz filter using a modified four-split CELC (MFC) metal-dielectric-metal structure with improved transmission performance is presented. The experimental results on THz time-domain spectroscopy (TDS) are in good agreement with simulations. Results show that the bandpass filter resonated at 0.315THz with substantial improvements in the low losses, steep skirts, high out-of-band rejection and slight in-band fluctuations.
