RobustPhysics makes it easy to define the volumes of multiple connected cavities from mechanical CAD and easy to superimpose the cable harness wiring defined from electical CAD. From that simple model, our patented hybrid statistical-deterministic solvers predict the maximum, mean and minimum E field in each cavity, and the differential mode (DM) cross talk in conductors and the common mode (CM) currents of each cable harness segment. Small details that can effect these results at high frequencies are not neglected; they are the quantitative, physical basis for the statistical uncertainty bounds of the model predictions. Our non-parametric statistical formulation means this is a single, direct solution - no repeated Monte Carlo iterations for converged statistics.
Model aims to support design with the full EMC engineer's toolbox
The statistical EMC model doesn't just provide quantitative assessment of design compliance, it also allows quantitative evaluation of design improvements, supporting a wide range of standard solutions in the EMC engineers' toolbox. It is this aspect that can truly deliver EMC design to the integrated E-CAD and M-CAD design process.
How much simpler, faster, better ?
A statiscally-reduced model for cable coupling to high frequency cavity reveberant E fields (typically 100 MHz - 10+ GHz) involves orders of magnitude less model variables (degrees of freedom) than a numerical, full wave solution to Maxwells' equations. The result is orders of magnitude less model building time (no cavity detail required; no numerical meshing required), orders of magnitude faster model solution time and orders of magnitude easier - and more statistically robust - prediction of maximum expected field levels.
How can statistical EMC simulation improve EMC testing ?
Statistical EMC simulation doesn't only benefit the system-level electro-mechanical design process; its also offers significant new opportunities in the EMC test / qualification process. Perhaps most powerful, it provides a quantitative basis for tailoring EMC environments - providing relief from CISPR and MIL-STD specifications when appropriate - AND reduces the number of system-level mock-up tests required to reproduce complex coupled field environments.
