This paper by Handel discusses use of ball lightning for THz stand-off detection of bio-chemical agents, presented at the International Symposium on Spectral Sensing Research at Stevens Institute of Technology. The research proposes that controlled or naturally-occurring ball lightning could serve as a coherent terahertz radiation source for remote detection of chemical and biological agents through their characteristic THz absorption signatures, exploring the potential application of atmospheric plasma phenomena to homeland security and defense sensing applications.
