MoM-SO: A fast and fully-automated method for resistance and inductance computation in high-speed cables

We present a fast and fully-automated algorithm to extract the series impedance of cables with round conductors, such as USB and HDMI cables. Our solution combines the method of moments with a surface admittance operator, and is much more efficient than a finite elements approach. Moreover, it is fully automated, owing to an adaptive scheme to automatically determine the discretization of the geometry in order to provide accurate results. Numerical tests on several types of cable demonstrate the excellent accuracy and speed of the proposed method.
