Dipolar-like antenna emission in the radiofrequency range by laser-produced plasma channels in air

Experimental evidence of a dipolar-like antenna emission in the radiofrequency range from a terawatt laser-produced plasma channel in air is, for the first time, obtained. The emitted frequencies exhibit resonances as a function of the plasma length. Possible applications for plasma fundamental para...

Beschreibung
Zusammenfassung:	Experimental evidence of a dipolar-like antenna emission in the radiofrequency range from a terawatt laser-produced plasma channel in air is, for the first time, obtained. The emitted frequencies exhibit resonances as a function of the plasma length. Possible applications for plasma fundamental parameter measurement, and the plasma heating approach, are discussed.
