The present disclosure provides a protective enclosure for electronic systems. The enclosure comprises a polymer-containing matrix and a metamaterial incorporated into the matrix. The metamaterial is tuned to a specific permittivity or permeability to absorb or reflect a particular frequency. The protective enclosure may be used to create a safe inner environment for electronic components while facilitating uninterrupted wireless communications to/from the outer environment. Additionally, the protective enclosure may be used to protect against electromagnetic interference. In particular, shielding metamaterials are configured individually or in combination to specifically shield (via reflection, absorption, etc.) against relatively wide bands of electromagnetic frequencies, while transparent metamaterials are configured specifically to pass electromagnetic signals within narrow bands of frequencies. This new approach resolves and vastly improves current shield solutions, such as Faraday cages. For example, tuned metamaterials may be configured across a variety of preconfigured frequencies, and can be constructed of lightweight materials.
