Abstract :
We present an experimental study of the magnetic Purcell effect in finite arrays of the wire metamaterial. By directly measuring the spatial-frequency map of the Purcell factor we explicitly demonstrate how the Purcell factor is enhanced at the Fabry-Perot resonances of the wire metamaterial block in microwave frequency range. The experimental results are in a good agreement with theoretical and numerical estimations.
