| Summary: | 碩士 === 大同大學 === 機械工程研究所 === 94 === The study purpose of this article is research in those common industry chassis of network and communication at present, it cuts the size of radiation network hole in the industry chassis which has the best choice of the shape and the way of arrangement to the result of control in the EMI/EMC. Why I do this research is because of electromagnetic wave that becomes seriously injury problem to people’s body & health so much today, and people face this problem now already more and more. But, so far, in industry chassis market, there is not so many articles were issued on it. So, in the thesis, we use the standard laboratory and instruments of EMI/EMC to proceed the serial tests of Square & Circular holes with many sizes and permutation of the normally specs in the industry chassis market. From these models, we can to understand the simulate status in the frequencies of 300kHz～1GHz and their true effects of the EMI/EMC. After a Series of experiment, we can know that the types and sizes of holes that the way of cover efficiency on circular holes is better than square holes!
Thus, it interests me to study this subject, and also I would like to present some my personal idea to the people who is interesting the same project reference.
