我们展示了在大气压下的空气中产生的一米长的线性等离子体柱的可调谐射频发射。短寿命的等离子体柱最初是通过飞秒成丝产生的，随后通过施加外部高压场转化为长寿命的放电柱。射频激励通过感应馈送到等离子体，并通过经典天线作为电磁辐射进行远程检测。 (C) 2012 年美国物理研究所。 [http://dx.doi.org/10.1063/1.4773492]
We demonstrate tunable radiofrequency emission from a meter-long linear plasma column produced in air at atmospheric pressure. A short-lived plasma column is initially produced by femtosecond filamentation and subsequently converted into a long-lived discharge column by application of an external high voltage field. Radiofrequency excitation is fed to the plasma by induction and detected remotely as electromagnetic radiation by a classical antenna. (C) 2012 American Institute of Physics.
