Abstract: Axions are an intriguing dark matter candidate, emerging from the Peccei-Quinn solution to the strong CP problem. Current experimental searches for axion dark matter focus on axion masses below 40$\mu$eV. However, if the Peccei-Quinn symmetry is restored after inflation the axion mass is predicted to be in the 100\,$\mu$eV range. A new project based on axion-photon conversion at the transition between different dielectric media is presented. The axion-photon conversion could be enhanced by a factor $\sim 10^5$ over a single mirror by using $\sim 80$ layers of dielectrics. Within a 10 T magnetic field this could be enough to detect $\sim 100$\,$\mu$eV axions with HEMT linear amplifiers. The proposed design for an experiment is discussed. Results from noise, transmissivity and reflectivity measurements in a prototype setup are presented. The expected sensitivity is shown.
