Invisibility as a superior self-protection tactic has long captivated the popular interest in both academia and industry. However, state-of-the-art invisibility cloaks typically need to completely wrap or shield hidden object, leading object that cannot interact with environment outside. This study develops precise efficient de-homogenization optimized-architecture produce high-performance, simple-parameter, fabricable remote cloak without constraints on geometry. As proof of concept, we demonstrate an open composed by four separate parts metamaterial can remotely hide arbitrarily shaped located at certain distance for mutually orthogonal directions incident waves. Additionally, extend this concept illusive device capability transforming any arbitrary into another one. Our work provides available strategies devices closer widespread range situ practical-oriented applications.

Metamaterials are a type of artificial material with microstructural features that characterized by physical properties not found in nature. originated the field electromagnetics and have now blossomed fields such as acoustics, mechanics optics. Negative Poisson’s ratio (NPR) metamaterials common mechanical metamaterials, also called auxetic long development history widely known for their tension-expansion compression-contraction deformation behavior. In this chapter, we reported revealed NPR effect mechanism, discussed applications three aspects. Most importantly, kinds new were introduced, i.e., lightweight high-strength multi-step intelligence metamaterials. For every topic, current future potentials given, especially fabrication process composite This content will help people understand concept continue to conduct research based on it.
