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 $\epsilon_r = 4.4$ and relative permeability $\mu_r = 1$, and low conductivity $\sigma = 0.02 S/m$. The low-loss upper layer has low permittivity $\epsilon_r = 1.07$ and $\sigma = 0.01 S/m$. 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.
