Physicists have created the first "frequency comb" in the extreme ultraviolet band of the spectrum, high-energy light less than 100 nanometers in wavelength. Laser-generated frequency combs are the ...

A Rydberg receiver and spectrum analyzer detects a wide range of real-world radio frequency signals above a microwave circuit including AM radio, FM radio, Wi-Fi and Bluetooth.A new quantum sensor can ...

Scientists have developed a frequency comb light source in the mid-IR wavelength band. These frequency comb light sources with an extended spectrum can be used for real-time, extremely high resolution ...

The combination of electric and magnetic fields at right angles produces radio waves. These waves occur at different frequencies, and the range of useful frequencies is called the electromagnetic ...
