Field uniformity analysis applying Aperture-field method

With the health effects of radio fields (RF) concerned by public, many experiments exposed to RF in vivo and in vitro were studied, but some results were in the contradiction. Of all the possible reasons RF Uniformity might induce the contractions in experiments. In this paper, we proposes the Aperture-field method to evaluate field uniformity applying IEC published standard IEC 61000-40-20. The analysis software was developed to analyze the field uniformity of region of interest (ROI) with the location far from aperture antenna VS the operating frequencies applying IEC 61000-40-20, and the results is verified by SEMCAD14.8. The analysis results from the software can be used to design the biological experiments exposure to RF which should keep RF uniformity in the ROI.
