Theme 1.6: Nanostructured Materials for Simultaneous Control of Light and Sound
This theme involves one project, summarized below, and the efforts of
two faculty. Strategically, this Theme is concerned with learning
how to build-in multi-functional nano-scale enabled properties in periodic
composites and other materials capable of also providing lightweight
and robustness. An example, proposed here for systematic study, is co-location
of complete electromagnetic and elastic band gaps in periodic composite
materials. This would allow the flow of light and sound through
the material to be simultaneously regulated. The research approach combines
modeling and simulation studies with experimental investigations. The
former will study the interactions of electromagnetic and elastic waves
with each other and with high order materials characterized by 3D nano-scale
periodic structures. Experiments will test modeling predictions,
and prove the core concept of synergistic photon-phonon interactions
enabled by nanostructures. Further capitalizing on modeling results,
experiments will be used to design, process and test promising photonic/phononic band
gap materials. Potential applications to Soldier survivability
include communications, thermal protection, and improved thermoelectric
devices for power generation or cooling.
