Abstract:
1. A damage locating system providing thermal protection, comprising: at least one chain substantially tiling an area that is to provide thermal protection, each said chain defined by an alternating arrangement of capacitors and inductors connected in parallel, each of said capacitors being an interdigitated-electrodes capacitor having a reflective surface associated therewith and each of said inductors being a spiral inductor having a reflective surface associated therewith, each said reflective surface adapted to face an environment from which thermal protection is sought wherein thermal protection is provided by each said chain; and a magnetic field response recorder for interrogating each said chain prior to damage thereof to establish a baseline frequency response for each said chain, and for interrogating each said chain after damage thereto wherein changes from said baseline frequency response for any said chain are indicative of damage thereto and a corresponding location thereof in each said chain.
