Abstract
A man-made magnetic material presenting magnetic response at different frequencies is made from non-magnetic conductive metal and formed in a four-way symmetrical structure consisting of four L-shaped units. A plurality of the four-way symmetrical structures is arranged to form a periodic array. The four-way symmetrical structure is formed at a size much smaller than the wavelength of incident light. Hence it is treated as an effective uniform medium in terms of the incident light. Such a novel planar structure can generate magnetic response in a wide range of bandwidth. The frequency band capable of generating the magnetic response also can be regulated and altered through control of the structural size.
