split-ring resonatorとは 意味・読み方・使い方

A split-ring resonator (SRR) is a component part of a Negative index metamaterial (NIM), also known as Double negative metamaterials (DNG) or Left-handed medium (LHM). They are also component parts of other types of metamaterial such as Single Negative metamaterial (SNG). SRRs are also used for research in Terahertz metamaterials, Acoustic metamaterials, and Metamaterial antennas. A single cell SRR has a pair of enclosed loops with splits in them at opposite ends. The loops are made of nonmagnetic metal like copper and have a small gap between them. The loops can be concentric, or square, and gapped as needed.
