DEVICE AND METHOD FOR CONTROLLING THE HEALTH OF A STRUCTURAL ELEMENT AREA AND A STRUCTURE ADAPTED FOR CONTROLLING HEALTH OF A STRUCTURAL ELEMENT AREA OD SAID STRUCTURE
摘要
<p>The inventive device (2) for controlling the health of a structure (1) which comprise a sigma conductivity imperfectly conductor material and anɛpermittivity dielectric material and is provided with a magnetic radiation source (4) generating a dielectric field in the structure, a sensor (5) measuring two components of an electric field along two directions forming a nonzero angle therebetween and computing (3) means producing the values sigma andɛon the base the two components.</p>
