Fig. 1. (a) THz optical path diagram based on metasurface. By controlling the phase delays of LCP and RCP waves by unit cells, metasurface can transmit the LCP and RCP components of the incident ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Independent manipulations of various properties of EM waves are crucially required in a wide range of ...

Terahertz (THz) waves, which are located between microwaves and infrared light in the electromagnetic spectrum, can pass through many materials without causing damage, making them useful for security ...

"Studying the relic radiation from the beginning of the universe is critical for understanding how the entire cosmos came to be and why it is the way it is." When you purchase through links on our ...

In this video, we explore how gravitational waves from the Cosmic Microwave Background (CMB) could illuminate the mysteries of the Big Bang. The discussion includes the CMB and its polarization, ...

Most fast radio bursts come from quiet galaxies like ours, suggests a recent study which traced 28 of them to their sources. Fast radio bursts are exactly what they claim to be: short, intense bursts ...
