Spectroscopy
OSU proposes to
apply the techniques of THz optoelectronics developed at OSU to three areas of
DoD relevance: 1) THz impulse scale ranging will be used to address fundamental
questions in electromagnetic scattering including target detection in clutter
and millimeter wave imaging; 2) In conjunction with fundamental investigations
on ranging, the study will develop materials/ surfaces with specific dielectric
properties in the millimeter and submm spectral region. These will include low
visibility materials and dielectrics whose response at THz frequencies mimics
that at GHz for use in table top ranging studies; and 3) The PIs propose to
apply the THz time-domain spectroscopy (THz-TDS) technique that they have
pioneered to previously intractable experimental problems in trace molecular
detection. The newly developed technique of Waveguide THz-TDS enables
characterization of materials at nanogram quantities.

Ranging
This renewal
project will focus on applying the THz-domain spectroscopy (TDS) technique that
has been pioneered to previously intractable experimental problems that cannot
be solved by the established and competing technique of Fourier Transform
Spectroscopy (FTS). The principal investigator will initiate new efforts in
THz-coherent transients and introduce the new areas of THz impulse ranging.
Compared to FTS, THz-TDS has some powerful advantages. The gated and coherent
detection of the THz (far-infrared) radiation is extremely sensitive, exceeding
that of liquid helium cooled bolometers by more than 1000 times, while the
thermal background (which plagues FTS measurements) is observationally absent.
In order to quantitatively demonstrate that THz-TDS is indeed the superior
far-infrared technique, the PI will perform a definitive experimental and
theoretical comparison between THz-TDS and FTS. The PI also plans to perform
coherent THz pulse propagation studies similar to those of low-intensity pulses
for the optical case. These observations would be unique in that the actual THz
field pulse will be measured, and that the THz pulse does not have a carrier
frequency but is composed of a broad frequency band for which the frequency
changes by more than 50 times from the lowest to highest values. Consequently,
it is not appropriate to describe the THz pulses in the usual way by a carrier
frequency and a time-dependent envelope; different concepts will be required
for their understanding. The new topic of THz impulse ranging is introduced by
the first direct experimental test of theoretical predictions for the surface
wave contributions to the scattering of electromagnetic radiation by dielectric
spheres. The PI plans to exploit this experimental capability by measuring the
complete propagation characteristics of the surface waves on spheres and
cylinders. By measuring the angular distribution of the scattered radiation,
the theoretical predictions of the THz glory will be tested. Experimental tests
of numerical predictions for more complex targets without analytic solutions
are planned.
