Studies on characteristics of absorbing materials

Presently the electromagnetic characteristics of absorbing materials have been partly studied on basis of Maxwell equations. However, a thorough study for a physics view-point is obviously insufficient. A new concept, power flux turning, is proposed. We analyzed the absorbing materials' characteristics by the method of the power flux, and found that power flux turning relates strongly with the absorbing materials' characteristics. Power flux turning keeps the absorbing materials' characteristics against improving.
