MAGNETIC PROPERTIES OF METAMATERIAL COMPOSED OF CLOSED RINGS

The magnetic properties of the metamaterial composed of both periodic and aperiodic closed rings are studied.Experimental results validate that metamaterials with 0 < µ < 1 can be nondispersive in a wide frequency range.The magnetic properties are insensitive to disorders of the closed rings, e.g., the position disorders and the size disorders.The related causality issue is also discussed.
