친환경 재료를 사용한 농업 폐기물 전파 흡수체

초록

Originally microwave absorbers are mainly used for military purposes or manufacturing anechoic chambers. However, as the use of high frequency devices increases gradually in nonmilitary circles, microwave absorbers have become more important. Microwave absorbers are classified variously by their uses, shapes or materials that form them. In general, conductive absorbing material, carbon particles, or magnetic material, ferrite, is used to make microwave absorbers. In this paper, microwave absorber was made using rice husk that is agricultural waste. To investigate the effects of mixture rate of materials, a variety of microwave absorbers with different mixture rate was made and tested. And the results are compared.
