Abstract: In order to find out the interference field of multi-beam surface plasma polaritons(SPPs),the theoretical interference model of multi-beam SPPs was deduced according to strict analytical expressions.The 2-D and 3-D lattice structure characteristics of SPPs interference were simulated and the resolution reached 1/6 wavelength.Its profile was the same as that of the ordinary laser beam interference field.It's very important for the multi-beam SPP lithography and manufacture of nano-scale optical devices.
