[edit] Overview
STL conducts research and development in four technical areas: electromagnetic materials and structures, electromagnetic apertures and scattering, optical and infrared physics and phenomenology, and secure information systems.
[edit] Organization
STL has four research thrust groups:
- Electromagnetic Materials and Structures Group (EMS)
- Specializing in design and fabrication of custom electromagnetic materials, composites and structures
- Electromagnetic Apertures and Scattering Group (EAS)
- Designing and developing innovative radiating apertures and assessing electromagnetic performance
- Optical and Infrared Physics and Phenomenology Group (OIPP)
- Correlating optical and infrared scattering properties with material composition
- Secure Information Systems Group (SIS)
- Creating enterprise information systems requiring state-of-the-art security
[edit] Research Areas
STL's main focus is the development of technologies for the management and control of multi-spectral signatures of objects under observation by sophisticated sensor systems.
The laboratory maintains an extensive numerical modeling and measurement capability for the design and development of thin, broadband antennas with tailored performance and controlled impedance surfaces for management/control of signature characteristics of systems and components. Numerical modeling has recently been extended to nano- and micro-magnetics phenomena with emphasis placed on modeling of nano particle nonlinear magnetics (NPNM). Novel techniques for correlating optical and infrared scattering properties with material composition have been developed and modeled for application to paint and photographic film characterization, optical signature control, and the evaluation of sensors and image based tracking algorithms.
STL maintains and operates extensive facilities for optical measurements specializing in laser and white light scatterometry, electromagnetic materials characterization, radar cross section measurements, antenna characterization, and computational electromagnetics. The secure information systems work is nationally recognized for the design, development, and deployment of enterprise information systems requiring state-of-the-art database, platform, and Internet security.
