【摘要】：基于光的波動性,提出了一種用于太陽能收集的螺旋納米天線結(jié)構(gòu),并利用時(shí)域有限差分法對其進(jìn)行分析。該天線結(jié)構(gòu)由兩個共面的阿基米德螺旋臂及基底介質(zhì)組成,分析了天線的輻射效率和極化特性。新的螺旋納米天線在400~1600nm的波長范圍內(nèi)(占太陽總能量的85%)可獲得高達(dá)74.49%的總輻射效率,高于先前學(xué)者提出的偶極子天線結(jié)構(gòu)。同時(shí),對于不同方向入射的線極化平面波,螺旋天線饋電間隙處可獲得同等量級的局域電場增強(qiáng),表明該天線能夠兼顧太陽光的任意極化特性。
[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.
