We study Rydberg atoms modulated by strong radiofrequency (RF) fields with a frequency of 70 MHz. The Rydberg atoms are prepared in a room temperature cesium cell, and their level structure is probed using electromagnetically induced transparency (EIT). As the RF field increases from the weak into the strongfield regime, the range of observed RFinduced phenomena progresses from AC level ...
