Wavy dark matter candidates, such as axion and dark photon, convert to ordinary photon. Since the frequency of the conversion photon of a meV mass particle is in the radio wave range (O(1 GHz) - O(100 GHz)) and has a narrow frequency peak, spectroscopic search is effective.
Since neither its mass nor its coupling to standard model particles is known, broad coverage of the mass region is...
