Due to the short wavelength for possible high‐resolution images and high frequency for fast imaging, the mmW technology has been extensively applied in human body scanners currently in the market. The mmW body scanners have achieved high‐precision scanning with much less harm to the human body. In particular, such mmW full‐body scanners have been very popular for airport security. They use the transmitted power of less than 1 mW and operate at a frequency range between 70 and 80 GHz.
