The Auger Engineering Radio Array (AERA) aims at the detection of air showersinduced by high-energy cosmic rays. As an extension of the Pierre Auger Observatory, itmeasures complementary information to the particle detectors, fluorescence telescopes and tothe muon scintillators of the Auger Muons and Infill for the Ground Array (AMIGA). AERA issensitive to all fundamental parameters of an extensive air shower such as the arrival direction,energy and depth of shower maximum. Since the radio emission is induced purely by theelectromagnetic component of the shower, in combination with the AMIGA muon counters,AERA is perfect for separate measurements of the electrons and muons in the shower, ifcombined with a muon counting detector like AMIGA. In addition to the depth of the showermaximum, the ratio of the electron and muon number serves as a measure of the primary particlemass.
