Abstract :
We demonstrate, numerically and experimentally, the generation of self-accelerating surface plasmon beams along arbitrary caustic curvatures by two-dimensional binary plasmonic phase masks. We examine both paraxial and non-paraxial curvatures accelerating along polynomial and exponential trajectories.
