Microwaves, a subset of radio waves, have wavelengths ranging from as long as one meter to as short as one millimeter, or equivalently, with frequencies between 300 MHz (0.3 GHz) and 300 GHz.

I didn't especially want to do that, but I learned a lot from it and a lot about engineering and microwaves. We were asked to build a radar at a wavelength of about 1 cm but found that 1 cm ...

New laser-based imaging technology is reportedly capable of capturing millimeter resolution from over 60 miles away.

The short wavelengths of the gamma radiation emitted in the initial explosion are believed to have become stretched due to the expansion of space into longer wavelength microwaves.

The signal distribution system at the Goldstone complex also provided the first example of an operational RF photonics link, in which RF, microwave or millimetre-wavelength signals are carried as ...
