On-chip grounded CPW line model with anomalous skin effect in THz band

This paper proposed and analyzed a new grounded coplanar waveguide (CPW) line model with anomalous skin effect for THz integrated circuits. The proposed CPW line model employs a donut-style multilayer conductor structure. The electromagnetic (EM) simulation of the proposed 50-Ω CPW line model results in the proportion to the frequency to powers of 0.5, 0.6, and 0.67 at 0.1-0.6 THz, 0.7-1.3 THz, and 1.4-2.0 THz, respectively. These results indicate the proposed CPW line model provides more accurate characteristics caused by anomalous skin effect on EM simulation.
