Description
We report on a search for hidden photon cold dark matter (HP CDM) using
a novel technique with a dish antenna.
We constructed two independent apparatus: one is aiming at the detection of the HP with a mass of $\sim5\times10^{-5}\,\rm{eV}$ utilizing a commercially available parabolic antenna facing on a plane reflector, and the other is for a mass of $\sim\,\rm{eV}$ which employs optical instruments.
From the result of the measurement, we found no evidence for the
existence of HP CDM and set upper limits on the photon-HP mixing parameter $\chi$.
