Abstract

Discrete plasmonic Talbot effect in the subwavelength metal waveguide arrays (SMWAS) is theoretically analyzed and numerically simulated. Based on the finite-difference time-domain technique, we discuss the influence of the structural parameters on the Talbot distance. By carefully choosing the geometry parameters, the Talbot distance decreases to about one third of the incident wavelength. The numerical simulation results agree with the theory of the discrete Talbot effect in the SMWAS.

摘要

本文从理论上分析和数值模拟了亚波长金属波导阵列（SMWAS）中的离散等离子体泰伯效应。基于时域有限差分法，我们讨论了结构参数对泰伯距离的影响。通过仔细选择几何参数，可以将泰伯距离减小到入射波长的约三分之一。数值模拟结果与 SMWAS 中离散泰伯效应的理论相符。
