Fractal Electrodynamics: From Super Antennas to Superlattices
We provide a selected overview of fractal electrodynamics by examining the properties of fractal antennas, arrays and apertures; and investigating the nature of electromagnetic wave scattering from fractal surfaces and superlattices.
Fractals offer an ideal blend of order and disorder that can be used in the design of robust antenna arrays with low or moderate side lobes. More recently, fractal geometry has also been used to design individual antenna elements suitable for multiband operation. We also investigate and review the diffraction of electromagnetic waves by fractal apertures.
Finally, we examine and review the scattering of electromagnetic waves from fractal surfaces and fractal superlattices. In each case fractals imprint their distinctive symmetry on interrogating waves. In this way fractal descriptors of an object are embedded in the scattered wave in such a way that they can often be extracted.
