摘　　要：为了设计出一个电路系统,使其具有期望的复杂纳米电路响应这一目标,研究使用串联和并联连接的纳米粒子结构,来充当纳米电路元件的可行性。具体分析了一对联接在一起的半圆柱体,这是由于其简单的几何结构更易于研究分析。此工作分两步完成,首先对联接在一起的两个不同介电常数的共振半圆柱体,应用准静态闭合形式的解析方式来证明其电压分布与纳米电路元件的等效关系;其次利用数值模拟求出其结果,并对这些结果做出分析与解释。We have investigated the possibility of connecting in series and parallel configurations plasmonic and/or dielectric nanoparticles acting as nanocircuit elements,with a goal for the design of a more complex nanocircuit circuit system with the desired response.In particular,we analyze a pair of conjoined half-cylinders,whose relatively simple geometry may be studied and analyzed analytically.This work contains two steps： Firstly,we derived a closed-form quasi-static analytical solution of the boundary-value problem associated with this geometry,to prove the effective voltage distributions may match that of nanocircuit elements;Secondly,we simulated the model with COMSOL,and analyzed the results to obtain a reasonable explanation.
