The boundaries between far infrared, terahertz radiation, microwaves, and ultra-high-frequency radio waves are fairly arbitrary and are used variously between different fields of study.Īt the high end of the band they are absorbed by gases in the atmosphere, limiting practical communication distances to around a kilometer. ![]() Rather, it indicates that microwaves are small (having shorter wavelengths), compared to the radio waves used prior to microwave technology. Frequencies in the microwave range are often referred to by their IEEE radar band designations: S, C, X, K u, K, or K a band, or by similar NATO or EU designations.
