Abstract
A structure which exhibits magnetic properties when it receives electromagnetic radiation is formed from an array of capacitive elements each of which is smaller, and preferably much smaller, than the wavelength of the radiation. Each capacitive element has a low resistance conducting path associated with it and is such that a magnetic component of the received electromagnetic radiation induces an electrical current to flow around the path and through the associated element. The creation of internal magnetic fields generated by the flow of the induced electrical current gives rise to the structure's magnetic properties.
