In the subwavelength optical integration, the excitation of surface plasmon polaritons (SPPs) propagation mode in waveguide is important. The structure is designed by using the surface electromagnetic wave holography (SWH) method, and the surface plasmon polariton waves are shaped. The well-designed structures can match plane surface plasmon polaritons waves to the symmetric and antisymmetric modes in double-wire waveguides. The effective excitation of the two modes in waveguide is realized. The designed structures are validated by the finitedifference time- domain method. The results show that two modes can be excited effectively. The excitation efficiencies of symmetric and antisymmetric modes can reach 8.7% and 10.8%, respectively, after optimizing structure parameters.
