Recently we demonstrated the fabrication and testing of a variety of RF-engineered passive transmission-line-based components designed for operation at terahertz frequencies and fabricated on thin (1 μm) silicon-nitride membranes. In this work we measure the transmission response of a coplanar-strip transmission line loaded with split-ring resonators up to 2.5 THz. We observe three dominate modes within the measured frequency range; the predicted LC resonator mode at 0.510 THz, a higher-order LC resonator mode at 1.03 THz, and a higher-order dipole mode at 1.85 THz. The LC resonator mode is investigated using a modified version of the standard lumped element model which incorporates the transmission line between adjacent meta-atoms using ABCD matrices.
