********* The X Band****************
Dr. Paul E. Dobler of Heilbronn, Germany discovered that turbulent water
emits powerful bursts of energy in the millimeter electronic wave band.
Turbulent motion of water generates millions of vortexes which act as
energy transmitters.
This energy waveband was once called the X-band by physicists as it
included the range from the infrared light band to the edge of the
microwave radio band. It was called the X-band because no one could
differentiate specific frequencies in this band. These energies have
very interesting properties.
Dr. Dobler discovered that energies in this waveband could cause certain
metallic crystals to emit photons of light which will expose certain
tpes of chromatic film.
Dr. Dobler made interferometers, resonators, and other devices that
could accurately measure the wavelengths emitted by water.
He was also able to measure millimeter wavelengths that are emitted by
crystals and magnets.
The exact techniques used by Dobler are described in his two books:
Biophysikalische Untersuchungen uber Stralung der Materie, Wunchelrute,
Elecktrische Wellen (Biophysical Experiments on the Radiation of matter,
Divining Rods, Electric Waves, 1939) and Physickalischer und
Photographischer machweis de Erdstrahlen Losung des Problems der
Wunschelrute (Physical and Photographic Proof of Radiation from the
Earth, 1934).
Unfortunately this great scientist's work was lost for many years due to
the destruction of scientific libraries in Germany during WWII.
Consequently the techniques used for their generation and detection rely
on a mixture of optical and radio wave techniques. Such systems might
use aerials,optical lenses,metal lenses, mirrors and circuits. Because
of this the technology is often referred to as 'quasi optics'.
At 0.1 THz (just above 10=B9=B2 Hz) the waves can be detected using a
radio which operates in much the same way as a car radio. The only
difference is that the aerial or antenna is only a millimetre long. The
whole radio can fit into an area of only 2 mm2.
This image (not shown) shows an artists impression of a simple terahertz
radio receiver. The pyramidal horn is made from stacked layers of etched
silicon. This focuses the terahertz waves onto the T shaped aerial at
the bottom which carries the signal to the detector Because of this the
technology relies on extremely precise components which until recently
have been incredibly expensive (it is not unusual for a single terahertz
component to cost more than 75,000 Euros).
Due to the expense, terahertz systems have only really been used in
areas of technology where cost is not an issue such as Space Science and
Astronomy.
Recently, however, the cost of manufacture has been dramatically reduced
such that newer everyday uses may be envisioned..
This has been possible by borrowing some of the technologies that have
been developed by the silicon chip industry. By using printing or
lithography, terahertz circuits and aerials can be manufactured cheaply
on silicon wafers. This means that it now may be possible, for the first
time, to build an array of terahertz detectors or pixels in much the
same way as a CCD camera. This technology has succeeded in takeing a
color terahertz photograph of a human hand.
