Surface current patterns in single patch antennas are imaged by means of photoexpansion nanospectroscopy performed with an atomic force microscopy probe and a broadly tunable quantum cascade laser system. The local ohmic losses lead to temperature increase of a thin polymer layer positioned in the cavity, which then expands.
