摘要：
A multicomponent iterative method is proposed for efficient source reconstruction based on magnitude-only and single-plane near field scanning. Compared with the conventional method filling the multicomponent data into a whole transformation matrix, the multicomponent iterative method can save huge calculation time by evenly reducing the size of the transformation matrix into magnetic group and electric group, without losing solution accuracy of the equivalent dipole moments. The accuracy and efficiency of the proposed source reconstruction is verified on a simulated patch antenna model. The proposed method is also applied to efficiently find the equivalent sources and reconstruct the surface electromagnetic field of a practical serpentine line. For a larger transformation matrix (depending on the factors such as the scanned field components, scanned points, and dipole numbers), the proposed iteration method shows higher efficiency.
