中文百科

极高频 Extremely high frequency

(重定向自Millimeter wave)

极高频英语:Extremely high frequency)是指波长短于超高频(SHF)的电磁波,波长由1mm到10mm。

毫米波所对应的频率范围是30~300GHz。主要应用于气象雷达、空间通信、射电天文等方面。也可能用于第五代移动通信系统(5G)。

英语百科

Extremely high frequency 极高频

(重定向自Millimeter wave)
Atmospheric attenuation in dB/km as a function of frequency over the EHF band. Peaks in absorption at specific frequencies are a problem, due to atmosphere constituents such as water vapour (H2O) and molecular oxygen (O2).
Millimeter wave fire control radar for CIWS gun on Russian aircraft carrier Minsk

Extremely high frequency (EHF) is the ITU designation for the band of radio frequencies in the electromagnetic spectrum from 30 to 300 gigahertz, above which electromagnetic radiation is considered to be low (or far) infrared light, also referred to as terahertz radiation. Radio waves in this band have wavelengths from ten to one millimetre, giving it the name millimetre band or millimetre wave, sometimes abbreviated MMW or mmW. Millimetre length electromagnetic waves were first investigated in the 1890s by pioneering Indian scientist Jagadish Chandra Bose.
