From: A design strategy to match the band gap of periodic and aperiodic metamaterials

The figure has been drawn by the Authors by means of Comsol Multiphysics and Inkscape.
Design strategy and analyzed geometries. (a) The composition of periodic and aperiodic metamaterials. (b–d) Building blocks supporting the mode separation concept: (b) “Quad”, (c) “Rhomb”, (d) “Circle”.
