【摘要】：基于光的波动性,提出了一种用于太阳能收集的螺旋纳米天线结构,并利用时域有限差分法对其进行分析。该天线结构由两个共面的阿基米德螺旋臂及基底介质组成,分析了天线的辐射效率和极化特性。新的螺旋纳米天线在400~1600nm的波长范围内(占太阳总能量的85%)可获得高达74.49%的总辐射效率,高于先前学者提出的偶极子天线结构。同时,对于不同方向入射的线极化平面波,螺旋天线馈电间隙处可获得同等量级的局域电场增强,表明该天线能够兼顾太阳光的任意极化特性。
[Abstract]:Based on the wave theory of light, a spiral antenna structure for nano solar collector was proposed, and analyzed using FDTD. The antenna structure by Archimedes spiral arm and the substrate two coplanar, analyzed the radiation efficiency of the antenna and polarization characteristics. The new nano spiral antenna in the wavelength range of 400~1600nm (% of total solar energy 85%) to get the total radiation efficiency is as high as 74.49%, higher than the previous proposed dipole antenna. At the same time, for different directions of incident linear polarized plane wave, local electric field in the helical antenna gap can obtain the same magnitude enhancement show that the antenna can take into account any the polarization characteristics of the sun.
