Fast prediction of radiation from high-speed/high-density connectors

摘要

A technique to quickly predict the electromagnetic radiation for large connector array is proposed in the paper. Based on the S-parameters from a small section of a much larger connector, the S-parameters can be expanded to characterize a connector with any number of sections by only taking the nearest two sections into account. The proposed method shows good agreement with the radiated emissions from a full-wave solver. This technique is much faster than typical full wave solvers, and, often, the complicated full connector is too large of a problem for most computer simulations. Included in the work, it is shown that the predicted radiated power from connector increases proportionally with up to 45 sections/wafers.
