Abstract :
A method for solving general CPW circuits including air bridges is proposed. The method generalizes the integral equation technique to nonplanar structures containing hybrid electric and magnetic currents. It also exploits the full-wave complex image technique to calculate the Green´s functions of this structure efficiently. The method, therefore, offers a substantial reduction in computer time and memory over many other full-wave methods. The accuracy of the method is checked by comparing the results with available FDTD-theoretical and experimental results for a coplanar-waveguide band-reject filter. Using only 92 matching points, the method gave very good agreement
