Abstract

The optical behavior of a structure consisting of graphene sheets embedded in media was studied, and the differences between the structure and ordinary birefringent crystal, double zero-reflectance point, were identified. We showed the changes in the optical behavior of the structure due to the existence of hidden photons. When a radiation illuminates the structure, only $\omega^2/\omega_p^2>1+\frac{m_X^2 c^4 \chi^2}{\epsilon_r\hbar^2\omega_p^2}$ can propagate through the structure. This provides a broadband platform for detecting hidden photons, where the sensitivity increases with the mass of the hidden photon.In contrast, if the mass of hidden photon is small, one can use a method similar to the light-shining-through-thin-wall technique. The structure is a platform to actively search for hidden photons since the operating point of the structure does not have to match the mass shell of hidden photons.
