농업용 폐기물을 사용한 친환경 전자파 흡수체

초록

As the use of high frequency devices has been increased gradually, the electromagnetic interference problems have been considerable and the importance of microwave absorber also has been increased. Marketed microwave absorbers usually use expensive materials displaying absorbing property such as carbon black, ferrite. In order to lower the cost of absorber, in this experiment, the dielectric property of compounds mixed with agricultural waste was investigated so that microwave absorber can be made by using this compounds. After the values of complex permittivity were measured in the various ratio of compounds, that results are compared.
