Exploiting Colloidal Metamaterials for Achieving Unnatural Optical Refractions

The scaling down of meta‐atoms or metamolecules (collectively denoted as metaunits) is a long‐lasting issue from the time when the concept of metamaterials was first suggested. According to the effective medium theory, which is the foundational concept of metamaterials, the structural sizes of meta‐...

Zusammenfassung:The scaling down of meta‐atoms or metamolecules (collectively denoted as metaunits) is a long‐lasting issue from the time when the concept of metamaterials was first suggested. According to the effective medium theory, which is the foundational concept of metamaterials, the structural sizes of meta‐units should be much smaller than the working wavelengths (e.g.,
