The Radio Extension of the Tunka Advanced Instrument for cosmic ray physics and Gamma Astronomy

In the present talk I discuss the modern technique of ultra-high energy cosmic-ray detection by measuring the radio emission produced during the development of air-showers induced by these particles. One of the successful implementation of this technique is the Tunka-Rex (Tunka Radio Extension) experiment operating since 2012 in the frame of the Tunka Advanced Instrument for cosmic ray physics and Gamma Astronomy (TAIGA) located in Siberia nearby Lake Baikal. I discuss the radio detection of air-showers, the methods for reconstruction of primary energy and mass composition, the main results of Tunka-Rex as well as benefits of multi-component detection of cosmic-rays in the frame of TAIGA.
