摘要： Two kinds of plasmonic lenses are proposed based on phase compensation. controllable foci focusing of the second kind of plasmonic lens can be utilized as dependence focusing. Two or four foci of the first kind of plasmonic lens and two Each kind of plasmonic lens is comprised of four sets of nanohole arrays, and two sets principles make the proposed plasmonic lenses show the different polarization the surface plasmon polaritons reaching to the focal spot. The different design optical switch and logic judgment. Theoretic analysis, numerical calculations and experiment measurement verify the focusing performance of our proposed plasmonic and the rotation angle of holes compensates respectively for the phase difference of of face-to-face nanohole arrays are planar symmetric. The adjustment of separation Polarization controllable plasmonic focusing based on
