Physics modeling
radar cross-section (rcs)
The strength of a RADAR signal from a metallic object indicates the object’s RCS; minimizing an asset’s RCS signature results in stealth technology. This project models and characterizes the RCS profile of a Cessna 172.
detonation modeling
Explosions are difficult to capture, much less model. This work merges results from a shock-shell modeling software (CTH) with modular ray tracing capabilities to characterize the optical effects of detonation fireballs.
ionosphere behavior
The ionosphere is fickle and difficult to understand for a variety of reasons. Buried within the data are the details needed to fully locate and partially characterize large over-the-horizon radar (OTHR) systems and vehicles.
em shielding via braided cable
Every discontinuous metallic interface can act as an accidental antenna, reradiating incident energy. One way to mitigate electromagnetic coupling on signal-carrying wires is through braided cables.
gaseous plumes
Gaseous plumes are difficult to model in their own right, but understanding them is important. To help understand them, hyperspectral imagery, weather data, and other tools can be utilized.
Novel imaging systems
Common camera systems can be tailored to create a new and capable system. One such system exploits the aperture stop to simultaneously form three independent images using existing camera geometries.
Chemically-activated resonators
The capabilities of micro-photonic sensors can be significantly enhanced by tailoring the materials used. In this research, initially passive sensors were enabled to aid in harsh chemical detection.
near-field electromagnetic coupling
Electromagnetic excitation of split ring resonators cause significant local field enhancement. By cleverly coupling coupling the strengthened EM fields, characteristics of the SRRs (ex. absorption bandwidth) can be enhanced.
