This NATO Advanced Research Workshop on "Inverse Methods in Electro- magnetic Imaging" has come at a time of greatly increased interest in using electromagnetic imaging methods as tools for remote sens- ing, material testing and medical diagnosis. Spurred by a combina- tion of recent advances in sensor and device technology spanning the entire m-to-sub-mm wavelengths, the infra-red, optical, ultraviolet and x-ray regions of the electromagnetic spectrum, the rapid devel- opment of radar polarimetry including the deployment of active/pas- sive sensors on spacecraft platforms, it has become...
