Super high frequency (SHF) is the ITU designation for radio frequencies (RF) in the range between 3 and 30 gigahertz (GHz). This band of frequencies is also known as the centimetre band or centimetre wave as the wavelengths range from one to ten centimetres. These frequencies fall within the microwave band, … See more Microwaves propagate solely by line of sight; because of the small refraction due to their short wavelength, the groundwave and ionospheric reflection (skywave or "skip" propagation) seen with lower frequency radio … See more The wavelength of SHF waves is short enough that efficient transmitting antennas are small enough to be conveniently mounted on handheld devices, so these frequencies are widely used for wireless applications. For example a See more • Tomislav Stimac, "Definition of frequency bands (VLF, ELF... etc.)".

WebWaves in the THF frequency band are known as terahertz waves, T-waves or T-rays. The upper limit is usually 3,000 GHz or 3 THz (1 THz = 1,000 GHz) although some sources designate it as 30 THz. Terahertz radiation begins at a wavelength of around a millimeter and proceeds into shorter wavelengths.
