Dielectric Metamaterials with Toroidal Dipolar Response
Dielectric Metamaterials with Toroidal Dipolar Response
Many biological structures, from macromolecules to proteins, as well as a number of solid-state systems including ferroelectric and ferro nano- and microstructures, possess static toroidal shapes. A theoretical study shows that the dynamic toroidal dipoles constructed from ionic crystals can be used to engineer metamaterials to control how electromagnetic radiation …
