More electromagnetic energy converged by the assembly of magnetic resonator and antennas
Abstract
The interaction of magnetic resonators connected by nano-antennas is studied for the first time. Compared to a simple magnetic resonator, the absorptance can be obviously much enhanced and more electromagnetic energy can be converged by the assembled magnetic resonator and nano-antennas (nano-strip). The nano-strip plays the role of both nano-antenna and phase tuner for propagating surface plasmon polaritons (SPPs). The interaction of localized
