System-Level Validation of Radiated Noise Source Characterization Using Only Near-Field Magnitude Information
To characterize the radiated noise sources in the radio-frequency interference simulations, a novel equivalent dipole source extraction method was proposed by our group previously. An iteration algorithm and the genetic algorithm work together to reconstruct an equivalent source using near-field magnitude information only while minimizing the number of dipoles needed. In this letter, the previously proposed equivalent dipole extraction algorithm is extended to efficiently extract an equivalent source of harmonics. Furthermore, the algorithm is verified using the actual product instead of simplified test boards. A rigorous and systematic validation process is proposed and conducted, which ensures the robustness and credibility of the extraction algorithm for future applications.
