Abstract :
In this paper, the technique of the reactive near-field to near-/far-field transformation has been proposed. The different thing compared with the previous work is that the environment of the semi-anechoic chamber with the ground plane was assumed during the transformation. The sources of electronic device are reconstructed from the detected reactive near-field. And then, the composite array source using the image theory is built, and then the transformation from the composite source to the near-/far-field are performed. For the verification, the simulated results have been utilized, and their results show small errors. Therefore, the proposed technique in this paper could be applied to predict the radiated field at 3 m or 10 m without the expensive large semi-anechoic chamber.
