When astronomers detected the first long-predicted gravitational waves in 2015, it opened a whole new window into the ...

A team of researchers from the University of Ottawa has developed innovative methods to enhance frequency conversion of terahertz (THz) waves in graphene-based structures, unlocking new potential for ...

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 ...

Announcing a new publication from Opto-Electronic Advances; DOI 10.29026/oea.2026.250229 .Programmable metasurface (PM), also termed as ...

This graphic shows the development of a soliton, which takes about 2.7 nanoseconds. Current begins passing through the center channel causing the magnetization to oscillate. The magnetization under ...

(Nanowerk Spotlight) Controlling how electromagnetic waves behave as they move through space is essential for technologies like wireless communication, radar, and remote sensing. Engineers have ...

A LPF transmits a multicycle fundamental pulse at ω, which produces a signal at 3ω after nonlinear interactions in a graphene-based sample. The LPF and HPF consist of a superposition of four ...
