The very broad bandwidth of low-loss optical transmission in a single-mode fiber and the recent improvements in single-frequency tunable lasers have stimulated significant advances in dense wavelength ...

Imagine taking the radio frequency properties of the dish antennas you see on rooftops and knitting them into a wearable ...

Researchers in China have harnessed the power of the Doppler effect to achieve a breakthrough in submarine detection.

Abstract: This paper reports measurements of the permittivity of moist air under different conditions of pressure, temperature, and water-vapor content taken at a frequency of 3,036 Mc. The method and ...

Sub-wavelength optics is the study of light on a spatial scale smaller than its wavelength. Conventionally, the minimum length scale on which a beam of light can operate is equal to half its ...

Researchers have defined the precise shape of a single photon, a huge leap forward in quantum physics and material science.

What are the benefits of green light vs red light therapy? “Red light therapy can be beneficial for overall skin health; it ...

People with photosensitive epilepsy could soon be able to watch TV without worry. Scientists in the UK have created glasses ...
