Optical Magnetic Response in a Single Metal Nanobrick
arXiv:1102.2692
Abstract
Anti-symmetric localized surface plasmons are demonstrated on a single silver nanostrip sandwiched by SiC layers. By employing the resonance of anti-symmetric localized surface plasmons, we enable single metal nanobricks to produce optical magnetism, in the blue and violet light range, as well as in a part of the ultraviolet light range. The physical mechanism is explained.
