Coplanar Waveguide

Model Description

A coplanar waveguide is a microwave semiconductor device, which is governed by maxwell's equations. The coplanar waveguide considered with dielectric overlay, i.e. a transmission line shielded within two layers of multilayer board with 0.5mm thickness are buried in a substrate with 10mm thickness and relative permittivity ${ϵ}_r=4.4$ and relative permeability ${\mu }_r=1$, and low conductivity $\sigma =0.02S/m$. The low-loss upper layer has low permittivity ${ϵ}_r=1.07$ and $\sigma =0.01S/m$. The whole structure is enlosed in a metallic box of dimension 140mm by 100mm by 50mm. The discrete port with 50ohm lumped load imposes 1 A current as the input to the one side of the strip. The voltage along the discrete port 2 at the end of the other side of coupled lines is integrated as the output.
