Abstract: The split ratio, defined as the outer radius ratio of the magnet to stator, has been investigated and optimized in surface-mounted permanent magnet (PM) machines having conventional/novel ...

Abstract: A split-ring resonator (SRR) array metamaterial of zero-index unit cell configuration has been proposed. The SRR is made up of four loops; r1, r2, r3, and r4, which are inductance related, ...
