【摘要】 等效局域型表面等离激元(ELSPs)是由结构色散引起的两个正介电常数介质交界面上的表面局域模式。本文基于ELSPs的中空圆柱形介质谐振器,分析了ELSPs的杂化现象,给出了基于ELSPs的中空圆柱形介质谐振器杂化形成的bonding和antibonding模式谐振频率的解析计算公式,并通过二维和三维模型的仿真验证了理论的正确性。更多还原

【Abstract】 Effective localized surface plasmons(ELSPs) are localized surface modes tightly confined at the interface between two positive dielectrics induced by structural dispersion.In this paper,a hollow cylindrical dielectric resonator based on ELSPs is taken as an example to analyze the hybridization of ELSPs.Theoretical calculations of the resonant frequencies of the bonding and antibonding modes are presented and verified by simulation results of two-dimensional(2 D) and three-dimensional(3 D) cases,respectively.The simulation results are in excellent agreement with the theoretical ones.更多还原
