论文摘要
由于天然材料的磁渗透性值较小，在光频率下，磁效应是一周。为此，对于光学元件中的实际磁性应用，天然介电材料可失业。我们已经表明，有可能在Janus介电中尺度粒子中诱导强烈的磁热点。 Janus粒子的基本思想是基于光子射流，耳语画廊波和固体浸入概念的效果的组合。模拟表明，对于折射率小于2的波长刻度粒子，H^2/e^2的对比度可能更多10，最大磁场强度增强大于1000。
At optical frequencies due to the small value of the magnetic permeability of natural materials, the magnetic effects are week. To this end, the natural dielectric materials are unemployable for practical magnetic applications in optics. We have shown that it is possible to induce the intense magnetic hot spots in a Janus dielectric mesoscale particle. The basic idea of the Janus particle based on a combination of the effects of a photonic jet, whispering gallery waves and the concept of solid immersion. Simulations show that H^2/E^2 contrast maybe more 10 and maximal magnetic field intensity enhancement is more than 1000 for a wavelength-scaled particle with refractive index less than 2.
