摘　　要：用几何位相调制金属表面等离子体(SPP)波是走向应用的重要途径.本文分别解析计算了螺旋波导管中的SPP波函数和绝热近似条件下的几何位相,进而给出了经几何位相调制后的波函数,直观展示了几何位相的影响.The use of geometric phase modulation of metal surface plasmon polariton(SPP)waves was an important approach to the application.In this paper,the SPP waves and the corresponding geometry phases in helical metal waveguide were calculated analytically.Based on the calculation results,the SPP eigenmodes modulated by the geometry phase were obtained and the influence of geometry phase was displayed intuitively.
