With satellite numbers soaring, laser communication is emerging as the solution to radio spectrum congestion in Earth’s ...

Researchers in Drexel University’s College of Engineering have developed a thin film device, fabricated by spray coating, that can block electromagnetic radiation with the flip of a switch. The ...

A wireless system that sends data through tiny lasers instead of radio waves reached a combined speed of 362.7 gigabits per ...

A closed door feels absolute. Light stays in one room, darkness settles in the next, and the boundary seems obvious enough to stop thinking about. Yet the same wall that blocks the glow from your ...

Fig. 1 THz wave generation from MoS2 through quantum interference. (a) Schematic diagram of THz wave generation from MoS2 under two-color light excitation at normal incidence. (b) THz waveforms ...

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...
