MAGNETIC PROPERTIES OF METAMATERIAL COMPOSED OF CLOSED RINGS

Abstract

The magnetic properties of the metamaterial composed of both periodic and aperiodic closed rings are studied. Experimental results validate that metamaterials with 0 < < 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.
