Description

Microwave sensors have been adapted to measure and create an image of the complex permittivity of lossy sheet materials non-destructively. The intended application is a portable probe which can map near-surface dielectric anomalies in various types of partially conductive sheet materials commonly found in aerospace equipment. Examples abound: radar-camouflage panels and textiles, coated canopies and moisture in non conducting composites. The need for such a probe originates in a number of different ways:
