Query: Sensitivity improvement in hidden photon detection using resonant
  cavities   Analogous to the light-shining-through-wall setup proposed for axion-like
particle searches, a pair of resonant cavities have been considered to search
for an extra U(1) massive gauge boson, called a hidden photon, which mediates
the interactions in the hidden sector. We propose a new cavity configuration,
consisting of a cylindrical emitter surrounded by a hollow cylindrical detector
to remarkably improve experimental sensitivity to hidden photon signals in the
$\mu$eV mass range. An extensive study was conducted to find the optimal cavity
geometry and resonant mode, which yields the best performance. In addition, a
feasible application of superconducting RF technology was explored. We found
the integration of these potential improvements will enhance the sensitivity to
the effective kinetic mixing parameter between the hidden photon and the
Standard Model photon by multiple orders of magnitude.
