Accurately measuring how radio signals propagate in electromagnetic materials is difficult, especially at lower radio frequencies where long wavelengths are difficult to study as they propagate through the small samples typical of experimental materials.

In work sponsored by the Air Force Research Laboratory, Georgia Tech Research Institute (GTRI) researchers have developed a computer-based simulation technique that permits the characterization of complex natural and engineered materials. The new software tools allow investigators to modify traditional approaches and to explicitly simulate the experimental apparatus, including the specimen under test, using a computer-based simulation and parameter extraction tool suite.
