Time-reversal techniques in wireless communications exploit the reciprocal nature of the propagation environment to focus energy both temporally and spatially at a desired receiver location. By ...

Physicists have long suspected that a peculiar quantum state lurks inside a class of materials known as kagome metals, but ...

Electromagnetic time reversal harnesses the reciprocal nature of wave propagation by recording scattered signals and retransmitting them in reverse time order. This process yields spatiotemporal ...
