为了研究MIM结构中腔的物理性质对SPP传播的影响，采用了对波导模式、谐振和反射系数以及相位分析的理论方法，讨论了腔长和厚度对SPP传播的相关参数的影响，仿真了MIM波导中电动势、腔长和反射系数等参数在结构中作用。结果表明，SPP传播产生的电动势能达到相对较大的1V ，激发产生的能场会有放大的作用；腔的有效功率变化与腔长变化一致，不同的腔厚度中腔长对SPP传播的结果趋势相同；近场中传播系数存在一个最大值。这一问题的分析与讨论对非线性THz光谱研究、纳米级光电探测、SPP模式的发生器、强局域场都具有一定的意义。

The effects of surface plasmon polariton (SPP) propagation on the physical properties of cavities in the MIM) structure was studies. Theory methods were drawed using waveguide mode, resonance, reflection coefficient, and phase. The effects of relevant parameters were discussed, including length and thickness, on cavities in SPP propagation. Moreover, the electromotive force (EMF) of Metal- Insulator-Metal (MIM) waveguide and the effect of structure by varying cavity length and reflection coefficient were simulated, etc. Results show that EMF, which is in the SPP propagation, becomes relatively larger than 1 V, and the energy field can be amplified. Moreover, the effective power increases with increased cavity length, and the cavity length has a similar effect on SPP propagation in different cavity thicknesses, with the propagation coefficient reaching a maximum value in the near field. In general, analysis and discussion of this text are significant in studies on nonlinear THz spectroscopy, nanophotoelectric detection, generation of SPP mode, and strong local field.
