摘要：

The possibility of an electron beam exciting surface plasmons in conducting metal is discussed in this paper.A planar perfect-structure with subwavelength holes is proposed.The phenomenon that mimicking surface plasmon waves can be excited and amplified by an electron beam is proved theoretically and numerically.The mechanism of transmission through a subwavelength hole array is exploited to enhance the interaction between the electron beam and the mimicking surface plasmons.
