This basically means that T-waves would need to be within a yard of the target but by being encoded on a laser induced plasma acoustic wave they go much further. Part of the technology behind the audio spotlight was to send sound wave pairs. Each wave being inverse of the other wave. Woody Norris the inventor of the audio spotlight called this, "laser sound", and this might be the, "laser induced acoustic wave" they are talking about.
Some have claimed EM waves can't travel as far as needed to do what is being done to us remotely at sizable distances. This video and the Audio spotlight are examples of how greater distances are accomplished.

Terahertz radiation
http://en.wikipedia.org/wiki/Terahertz_radiation
It is synonymously termed submillimeter radiation, terahertz waves,
terahertz light, T-rays, T-light, T-lux, THz. The term typically
applies to electromagnetic radiation with frequencies between
high-frequency edge of the microwave band, 300 gigahertz (3×1011 Hz),
and the long-wavelength edge of far-infrared light, 3000 GHz (3×1012
Hz or 3 THz). In wavelengths, this range corresponds to 0.1 mm
(or 100 µm) infrared to 1.0 mm microwave. The THz band straddles
the region where electromagnetic physics can best be described by
its wave-like characteristics (microwave) and its particle-like
characteristics (infrared).
I now realize that I made a few wave guides in this range back in the 1980's.
I actually still have one or two.
