OptoMetrix has recently developed a technique for localized sampling of material properties in the microwave regime. This microwave spectroscopy technique was developed under an Airforce contract to extract microwave properties of stealth materials.  With specialized near field probes, the broadband microwaves from 0.1GHz to 20GHz allow sampling of the spectrographic properties of the material.  The probe can be scanned over an area to produce an image. Any changes of the material microwave properties can be detected.

A portable test instrument will become available in late 2004.
