Abstract: Abstract: Backward and forward scattering of surface plasmonic wave interactions from gold nanobumps on the surface of a 30-nm gold thin film demonstrate three-dimensional (3-D) focusing and diverging properties. Fan-shaped forward scattering of an individual nanobump is observed. A quarter-circle structure composed of nanobumps is exploited to manipulate scattering from each nanobump. Experimental results show that 3-D propagation vectors generated by the gold nanobumps with their heights of 16 nm can deflect the surface plasmonic waves to produce 3-D focusing at 3.6 μm above the surface of the gold film. We clearly demonstrate that 3-D forward and backward focusing from gold nanobumps are with different amplitudes and directions of the vertical propagation vectors.
