Advanced Concepts Laboratory (ACL)

Advanced Concepts Laboratory (ACL)

Formerly the Signature Technology Laboratory (STL)


ACL focuses on the transition of basic academic research in electromagnetic effects and devices into prototype systems that demonstrate new capabilities. The capabilities of interest are typically sensing, scattering control, electromagnetic field control and measurement, and signal filtering, all of which support GTRI’s core system-level capabilities. In support of this mission ACL conducts research and development over a broad range of topics, including:

  • Electromagnetic materials and structures
  • Electromagnetic apertures and scattering
  • Optical and infrared physics and phenomenology
  • Advanced signal processing and geo-location of emitters Passive ranging and passive radar
  • Advanced waveforms for electronic attack and protection
  • Terahertz sources
  • Magnetic and dielectric meta-materials
  • The design, fabrication, and integration of ion-based quantum computer components

The laboratory maintains world-class numerical modeling and measurement capabilities to cover electromagnetic phenomena from quasi-static to ultraviolet (UV) wavelengths. Extensive facilities are devoted to:

  • Optical measurements specializing in laser and white-light scatterometry
  • Electromagnetic materials characterization
  • Radar cross-section measurements
  • Antenna characterization
  • Computational electromagnetics

Specific ACL prototypes that have recently extended the state-of-the-art include: electrically thin, broadband antennas; self-adaptive antennas; near-field measurement systems that allow for accurate scattering measurements in non-ideal environments; radio frequency (RF) and infrared (IR) custom meta-material structures for management/control of signatures; planar ion traps and ion junctions for quantum computer applications, a multi-static radar system, and jammer-robust waveforms for use in future radars.
