چکیده
|
The novel plasmonic lenses based on slanted nanoslits have been proposed theoretically. the slanted nanoslits with different slant angles can provide unequal propagation distances for the surface plasmon polaritons excited by incident light. the phase retardation for wavefront shaping can be obtained to realize constructive interference on a preset single spot. we can actively modulate the position of the optical focus by adjusting the slits slant angles properly. the simulation results of the finite element method are used to verify our proposals.
