In 1992, Steven Turner founded Analogic Engineering, Inc., (AEI).
AEI develops and manufactures ultrasonic nondestructive test equipment, and instrumentation for control and measurement systems. In 2002, AEI received an NSF SBIR Phase I Feasibility Study grant to develop a proprietary Electro Magnetic Acoustic Transducer (EMAT) and instrumentation that uses variable polarization shear waves to measure longitudinal stress in steel. In 2010, AEI received another NSF SBIR Phase I Feasibility Study for their research titled: “Using Ultrasonic Shear Polarization Contrast to Locate and Size Defects."
AEI developed a mathematical model to prove feasibility of detecting and sizing defects in steel structures and components using the EMAT and custom instrumentation and software.
