Chip-Scale Floquet Topological Insulators to Enhance 5G Wireless Communications

Chip-scale Floquet topological insulators to enhance 5G wireless communications
This schematic (left) shows the implementation of our Floquet PTI, the image in the middle shows the actual device, and on the right we show measurements demonstrating the robust propagation of electromagnetic signals across the device. Credit: Nagulu et al.

Floquet topological insulators are materials with topological phases that originate from tailored time-dependent perturbations of their crystal structure. These materials have been proved to feature highly unusual electron conduction properties...
