| contents | In this letter we report a proof-of-concept terahertz band-stop filter constructed from split-ring resonators that has a center frequency of 1.06 THz and a -3 dB bandwidth of 0.36 THz. The design consists of nine split ring resonators of varying radii (3 x 13 um, 3 x 14 um, 3 x 15 um) that are placed between the conductors of a coplanar stripline transmission line. The response of the filter is measured using a modified terahertz time-domain spectrometer and we find reasonable agreement between simulation and experiment. This work demonstrates the viability of using varying-radii split-ring resonators as discrete sub-wavelength filter elements for terahertz systems. |
