Radio Pulse Emission in Air Showers and Dense Media

Presenter: E.R. Lusczek (lusczek@physics.umn.edu), usa-lusczek-E-abs1-HE15-poster The different radio frequency (RF) pulse generating physics processes will be explored with the primary distinction between the air shower emission and the Askaryan emission in dense materials. During the 1960s and 1970s, Cosmic Ray physics saw a flurry of activity surrounding the radio emission of air showers. These kinds of experiments eventually ended because of difficulties in measuring signals and interpreting results. Interest in radio detection has been renewed in part due to the Askaryan effect, which predicted that the radio signal becomes dominant for showers in dense, radio transparent material such as ice, salt, or lunar regolith.
