【Abstract】 It is shown that various closed circuits formed by line-shaped metallic particles in composite induce great permeability.Effect of temperature on magnetic response is weak.Based upon effective medium theory,electric and magnetic response of composites containing line-shaped tungsten particles are addressed.Microwave absorbing composites are designed and optimized,which may be applied in high temperature circumstances.更多还原
