In the simulation, the CPW lines were modeled using an electric field applied across the RF strip and two ground electrodes. This setup was achieved in COMSOL by establishing two lumped ports and creating a two-port network essential for analyzing the s-parameters. These ports were designed to simulate the electric field between the RF line and the ground electrodes of the CPW, as illustrated in Figure ). Critical material properties, such as the conductivity and relative permittivity of fused silica and gold, were obtainted from the COMSOL material library. All simulations were performed with finite metal thicknesses and conductivities to ensure a realistic representation of the CPW behavior under practical conditions.
