标题： Directional visible light scattering by silicon nanoparticles

摘要： 可见光谱范围内球形硅纳米颗粒的方向性光散射首次被实验演示。 这些独特的散射特性是由于在单个纳米球内同时激发磁偶极子和电偶极子共振并发生相互干涉而产生的。 通过改变光波长和纳米颗粒的大小，可以控制远场辐射图案的方向性。 在可见光波长下，实验上可以获得高于6的前向-后向散射比。 这些硅纳米颗粒的独特性质使其在设计新型低损耗可见光和电信范围的纳米天线器件方面具有前景。 显示英文摘要

摘要： Directional light scattering by spherical silicon nanoparticles in the visible spectral range is experimentally demonstrated for the first time. These unique scattering properties arise due to simultaneous excitation and mutual interference of magnetic and electric dipole resonances inside a single nanosphere. Directivity of the far-field radiation pattern can be controlled by changing light wavelength and the nanoparticle size. Forward-to-backward scattering ratio above 6 can be experimentally obtained at visible wavelengths. These unique properties of silicon nanoparticles make them promising for design of novel low-loss visible- and telecom-range nanoantenna devices.
