The study of the resonant behavior of silicon nanostructures provides a new route for achieving efficient control of both electric and magnetic components of light. We demonstrate experimentally and numerically that enhancement of localized electric and magnetic fields can be achieved in a silicon nanodimer. For the first time, we experimentally observe hotspots of the magnetic field at visible wavelengths for light polarized across the nanodimer's primary axis, using near-field scanning optical microscopy.
硅纳米结构的共振行为研究为实现光的电和磁分量的有效控制提供了新途径。我们通过实验和数值模拟证明，硅纳米二聚体可以增强局域电场和磁场。我们首次使用近场扫描光学显微镜实验观察到了沿纳米二聚体主轴偏振的光在可见波长下的磁场热点。
