Interaction of water surface waves with periodic and quasiperiodic cylinder arrays

What is it about?

Highlights • Inspired by transformation optics, quasiperiodic array water waveguides investigated. • Propagation through arrays supports a transformation approach to waveguide design. • Near 100% redirection of wave energy achieved with minimal arrangements. • Bragg resonance and Bloch band gaps in quasiperiodic lattices identified. • Bragg diffraction consistent with rotational symmetry.
