| Research Abstract |
To improve a comfortable residential environment under the increasing electro-magnetic environment, a woody electromagnetic wave absorber is one possible approach to solving the unwanted radiation or to reduce its impact on the surrounding area. The basic design of adjusting methods on indoor electro-magnetic wave absorber concerning about material constants and electromagnetic absorption characteristic is examined and the methods give good results to design indoor powder-type magnetic wood wave absorbers for a specified absorp-tion frequency. The two methods are proposed, one is a method to impregnate magnetic fluid to wood powder and the other is to heat the powder type magnetic wood in low temperature. Both methods change permittivity and can shift the matching frequency without changing the thickness and the weight of the board.
The results from our studies can be used to design indoor powder-type magnetic wood wave absorbers for a specified absorption frequency.
