Abstract

In this paper, we show that compared with the conventional transformation elastodynamics, the method based on physical interpretation of form-invariance can provide more flexibility in material design. As a result of this flexibility, the impedance-matched condition for both S and P waves in perpendicularly incident cases exists, thus the isotropic homogeneous elastic wave concentrator can be designed. Samples are conceived and validated by numerical simulations.
