A dendritic compound of the following structure: PDn-Z-L is disclosed. The plurality of connecting superconducting wires 101 cover the inclined surface sections 213b of the reinforcement insulating layer 213 formed thicker than the radius of the cable cores 11 of the superconducting cables 10. Advantageously, composites may be flexed, stretched, or bent without significant dusting or loss of insulating properties. One aspect of the invention relates to selecting a root frequency and then, via a mathematical operation or algorithm, calculating a single component frequency or a plurality of frequencies that lie in the infrasonic or ultrasonic range. When such an occurrence happens, a notification is directed to the salesperson.
