Abstract

This paper presents a 3D metamaterial with engineered zero modes, experimentally demonstrating its transformable static and dynamic properties. Seven types of extremal metamaterials, ranging from null-mode (solid state) to hexa-mode (near-gaseous state), are reversibly transformed. Tunable wave manipulations are investigated in 1D, 2D, and 3D systems.
