| 摘 要： | 设计了加载MIM波导的Otto结构研究SPPs的传输和衰减特性,应用球面EM场的解法求解了整个介质区域的本征函数的特征值。对SiO2厚度分别为750 nm和1 500 nm的设计结构进行了仿真,结果表明:750 nm改进结构的TM0传播常数达到了1.541,衰减系数仅仅为2.80;随着SiO2层介质厚度的减小,反射系数随之增大,且不同金属介电常数的谐振方向变化趋势一致;随着腔厚度的减小,在反射相位减少的同时其存储能量也随之减少。

| Abstract: | The MIM waveguide loaded Ottos structure was designed to research the characteristics of transmission and attenuation of surface plasmon polaritons (SPPs), and the sphere EM field of the solution was used to achieve eigenvalue of solution in the entire media area. The structure with 750 nm and 1 500 nm media were simulated. The results show that TM0 propagation constants reaches 1.541 in the 750 nm improved structure. With the reduction of the SiO2 dielectric thickness, the reflection coefficient increases, and the resonator direction with different metal dielectric constant have the same trend. With the reduction of the cavity thickness, the reflection phase and the stored energy also reduce. |
