A tunable metamaterial is a metamaterial with a variable response to an incident electromagnetic wave. This includes remotely controlling how an incident electromagnetic wave (EM wave) interacts with a metamaterial. This means the capability to determine whether the EM wave is transmitted, reflected, or absorbed. In general, the lattice structure of the tunable metamaterial is adjustable in real time, making it possible to reconfigure a metamaterial device during operation. It encompasses developments beyond the bandwidth limitations in left-handed materials by constructing various types of metamaterials. The ongoing research in this domain includes electromagnetic materials that are very meta which mean good and has a band gap metamaterials (EBG), also known as photonic band gap (PBG), and negative refractive index material (NIM).

The present disclosure provides a protective enclosure for electronic systems integrating two key components: a preconfigurable polymer matrix and a tunable metamaterial. The polymer matrix forms a lightweight, structurally robust foundation with excellent mechanical properties and design flexibility, configurable for specific application requirements. Integrated within this matrix is a highly adaptable metamaterial system, precisely tunable to interact with electromagnetic energy in customized ways. By adjusting its permittivity and permeability, the metamaterial can selectively repel or absorb specific frequencies of electromagnetic radiation, allowing targeted shielding against harmful interference while permitting desired communication signals to pass through. This integration overcomes limitations of traditional electromagnetic shielding approaches, offering enhanced design flexibility and customization for various electronic applications. The use of carbon nanoparticles enables fine-grained control over the metamaterial's electromagnetic properties, creating protective enclosures that effectively manage electromagnetic energy while remaining lightweight and mechanically robust.
