The Georgia Tech UltrawideBand Technology Center of Excellence is
directed to study of electromagnetic phenomenology associated with
ultra wideband and high power electromagnetic waveforms. The institute
supports programs in: numerical model/simulation of UWB phenomena;
source-radiator-receiver aperture design assembly and testing;
development and proof of concept in measurement for UWB electromagnetic
propagation and electromagnetic coupling too materials and structures;
and investigations in nonlinear electromagnetics.
Discussion of ultra wideband electromagnetic phenomena, applications and
measurement has been an active and sometimes controversial subject for
20 years [1-4]. Even definition of "ultra wideband" has often been
argued. Specific controversy surrounds claims of UWB advantages for radar
target identification and discrimination, measurement of material properties
and electromagnetic response of appliqués. In the last 10 years,
UWB communication, receivers and transmitter configurations, thin antennas
and high power sources,
High Power Electromagnetic Fields,
have achieved quantum leaps in capability. Electromagnetic material and
structure performance has been extended by
and new phenomena in negative index-left handed materials and other
electromagnetic structures that have resonant responses to incident
electromagnetic waves. Power-aperture products and power densities in
current and future systems must include consideration of nonlinearity in
electromagnetic interaction with materials, structures and microwave devices.
Appropriate study at high powers requires extension of existing codes,
improved measurement facilities, antennas, sources, etc. In summary it is
necessary that the electromagnetic modeling, demonstration and implementation
cycle be restarted.

The Georgia Tech UWB center of excellence (CoE) recently completed a
comprehensive review of UWB literature. That review forms one basis for
the implementation of the CoE's research plan. The document is being
made available to the UWB research community at
