As more and new power electronics with high switching frequencies are used in power-electronic equipment on ships other platforms, the wideband radiation that gives off could affect sensitive platform. Therefore, it is crucial to accurately model characterize its properties predict field distribution near such equipment. The traditional equivalent dipole method commonly at a single frequency. It difficult apply this applications, precision of array modeling each frequency insufficient. Additionally, acquiring near-field phase data necessary for comparable through practical measurement frequently difficult. To solve above problems, paper proposes an hybrid equipment’s broadband characteristics. Starting finite points wideband, employs global optimization algorithm find best array, which characterizes Furthermore, interpolation technique Finally, test numerical examples demonstrate method’s accuracy effectiveness.
