In this paper, two disordered temporal multilayered structures are proposed based on dispersive Lorentzian materials for amplification of electromagnetic waves in the frequency range of [25 GHz, 38 ...

The rapid advancement of the Information Age needs the development of intelligent electromagnetic interference shielding materials that respond to real-time environmental alterations. Herein, we ...

A 4D-printed microwave absorber uses heat to reshape itself and strengthen internal energy loss, enabling tunable shielding after fabrication.

When we look in a mirror, we are used to seeing our faces looking back at us. The reflected images are produced by electromagnetic light waves bouncing off of the mirrored surface, creating the common ...

Electromagnetic waves are packets of energy travelling all around us. Some of these waves have lots of energy, and some have less. We call the lowest energy electromagnetic waves radio waves. There’s ...
