Abstract
This cover image shows the reconfigurable terahertz metamaterials where artificial toroidal metamolecules and traditional MEMS bi-material cantilever structures are integrated within the same unit cell. This enables enhancement of the toroidal dipole response through reorientation of the metamolecules by thermal actuation. These results, presented by Xin Zhang, Richard D. Averitt, and co-workers in article number 2101215, demonstrate the use of bi-material cantilevers to realize a tunable toroidal moment with potential applications in sensing and next-generation communication technologies.
