Improved Transmission Line Parameter Calculation through TCAD Process Modeling for Superconductor Integrated Circuit Interconnects

Propagation of picosecond pulses on superconducting transmission line interconnects *

“…Methods that apply to arbitrary geometries include that of Herbst et al who developed a numerical solver that extracts transmission line parameters from the meshed model, but assumes a lossless two-fluid superconductor that limits the method to non-dispersive lines [28]. Sheen et al designed a custom 3D finite element modeler capable of solving lossy PTL with arbitrary cross-section [29], but use a two-fluid model for the superconductor complex conductivity that limits applicability to GHz frequencies.…”
