![]() ![]() Gives good agreement with both measurements and simulations. Material system, we describe an analytical model of the CPW properties that Toįacilitate the design of distributed microwave devices based on this type of Simulations, we determine that the strontium titanate film has a dielectricĬonstant of $1.1 \times 10^3$ and a loss tangent of not more than 0.009. Comparing the measured transmission coefficient to numerical zo depends upon the geometry and the material of the transmission line. the line height, the geometry of the towers and phases, the soil characteristics and the cable properties) while considering the earth-return current and the skin effect in the wires. We fabricated andĬharacterized an approximately $50$ $\Omega$ CPW device with two half-wave stub One of the most basic parameters of a transmission line is zo, its characteristic impedance. The electrical parameters of transmission lines can be calculated as a function of the line structure and the physical characteristics of the lines (e.g. Range of CPW widths, from the nanoscale to the macroscale. Possible to realize a $50$ $\Omega$ characteristic impedance across a wide Wafer-scale fabrication and maximizes process compatibility. The use of strontium titanate on silicon enables On a bilayer substrate consisting of 100 nm of epitaxial strontium titanate on Thin film is patterned in a coplanar waveguide (CPW) transmission line geometry Superconducting nanowires on high permittivity substrates. Wavelength more than 150 times smaller than the free space wavelength using Attenuation is due to finite conductivity in conducting regions II and IV.
