Abstract This study presents a numerical framework for analyzing dispersion and wave propagation in spatiotemporally modulated metamaterials. A one-dimensional periodic spring–mass system with space- and time-dependent...

Abstract Plate lattice metamaterials offer higher strength-to-weight efficiency than traditional truss lattices. Their optimization, however, is challenging when having more parameters and multiple objectives. Here, we p...

Abstract Metamaterials have gained much attention due to their exciting characteristics and potential uses in constructing valuable technologies. This paper presents a double negative square resonator shape metamaterial ...

Abstract We establish an intuitive connection between transformation optics (TO) and the classical invariants of étendue and radiance. Through explicit application of the optical-metric formulation of TO, we demonstrate...
