Abstract

Negative refraction and flat lens focusing of elastic waves has been recently demonstrated experimentally, though restricted to periodic structures where dispersion relations are readily available for prediction and design of superlenses. This is not possible anymore when considering quasiperiodic structures. Here we demonstrate quasicrystal platonic superlensing of elastic waves in perforated metallic thin plates, opening new possibilities for applications of quasi-periodic structures in elastic waves.
