摘要

本文研究了椭圆型二聚体纳米天线几何优化的电学性质。数值计算基于时域有限差分法(FDTD)。考虑了三种不同几何参数的椭圆型二聚体纳米天线，即水平二聚体、平行二聚体和平行-水平二聚体。我们发现，在一维双臂光栅系统中嵌入水平二聚体的等离子体纳米天线与其他等离子体纳米天线相比，具有较强的电场增强作用。

The study of plasmonic elliptical dimer nanoantennas with different geometry

In this paper, the electrical property of a geometric optimization with elliptical shape dimer nanoantennas has been studied. Numerical calculations are based on the method of finite-difference time-domain (FDTD). Three types of elliptical shape dimer nanoantennas with different geometrical parameters were considered, namely, horizontal dimer, parallel dimer, and parallel-horizontal dimer. We have found that plasmonic nanoantennas with the horizontal dimer embedded into a 1D double-arm grating system provide strong electric field enhancement as compared with the others.
