An efficient computational design optimization method, combining full-wave electromagnetic simulation in COMSOL Multiphysics® software with a space-mapping (SM) algorithm implemented in MATLAB® software. 

The authors analyze the computational procedure specified for Channel Operation Margin (COM) and compare it to traditional statistical eye/BER analysis and propose a modification to the COM procedure that eliminates these problems without considerable work increase.

Multi-tone testing has many benefits. While the multi-tone methodology was initially implemented to increase the speed of immunity testing, it has been found that this method also improves equipment efficiency, offers greater flexibility to truly test the equipment (EUT) under real world threat conditions, and can be fully compliant to standards.
