摘要： The present invention relates to planar materials having bandgap properties. The materials are formed by depositing conductive fractal patterns (Figs. 1A, 1B) on a non-conducting substrate. The bandgap locations(s) are defined by parameters including the number of fractal levels, and the dimension of the fractal mother element (Specification, page 6). The bandgaps can also be controlled by injecting current into the conducting pattern.
