M band can refer to two different regions of the electromagnetic spectrum, in the radio and near-infrared.
Radio
The NATO M band is the range of NATO for electronic countermeasure (ECM) applications.[1][2] This is equivalent to wavelengths between 5 mm and 3 mm.
The NATO M band is a subset of the EHF band as defined by the ITU.[3] The NATO M band intersects with the V (50–75 GHz) and W band (75–110 GHz) of the older IEEE classification system.[4]
Infrared astronomy
Atmospheric windows in the infrared. The M band is the transmission window centred on 4.7 micrometres
In infrared astronomy, the M band refers to an atmospheric transmission window centred on 4.7 micrometres (in the mid-infrared).
