The assessment of electromagnetic radiation to electronic equipment in Civil Aviation Building

This passage is to assess the electromagnetic sensitive characteristics of the electronic equipment in Civil Aviation Building. The effects of electromagnetic radiation are from the internal radiation of subway station and the surroundings. Thus, we need to measure for the subway station firstly. Then, through the measurement of environment in Civil Aviation Building, we get the environmental level of the building before the establishment of the subway station. By means of HFSS and calculation, the distribution of electromagnetic field reaching the ground from the station can be obtained. Adding what we get to the original environmental level is the total distribution of electromagnetic field. Finally, we compare the results with the sensitivity limits and analyze the potential interference.
