Abstract

By employing the pseudospectral time-domain (PSTD) simulation technique, we analyze the propagation of monochromatic light through a macroscopic scattering medium. Simulation results show that, monochromatic light can be directed through a scattering medium and focus into a narrow peak; a range of wavelengths has been simulated. Furthermore, we compare: i) focusing monochromatic light through a macroscopic scattering medium, and, ii) focusing monochromatic light through vacuum. Based upon numerical solutions of Maxwell's equations, we demonstrate: with a fully-surrounding wavefront of specific amplitude and phase, sub-diffraction focusing can be achieved with monochromatic light, with or without the presence of a scattering medium.

摘要

通过采用伪谱时域(PSTD)模拟技术,我们分析了单色光在宏观散射介质中的传播。模拟结果表明,单色光可以被引导通过散射介质并聚焦成一个窄峰;已经模拟了一系列波长。此外,我们比较了:i)通过宏观散射介质聚焦单色光,以及ii)通过真空聚焦单色光。基于麦克斯韦方程组的数值解,我们证明:利用具有特定振幅和相位的全包围波前,无论是否存在散射介质,单色光都可以实现亚衍射聚焦。
