对硅纳米结构共振行为的研究为实现光的电和磁分量的有效控制提供了一条新的途径。我们通过实验和数值计算证明了在硅纳米二聚体中可以实现局域电场和磁场的增强。对于第一次，我们实验观察热点的磁场在可见波长的光偏振的纳米二聚体的主要援助，使用近场扫描光学显微镜。
The study of the resonant behavior of silicon nanostructures provides a new route for achieving efficient control of both electric and magnetic component 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 aids, using near-field scanning optical microscopy.
