This book deals with the design and analysis of fractal
apertures in waveguides, conducting screens and cavities using
numerical electromagnetics and field-solvers. The aim is to obtain
design solutions with improved accuracy for a wide range of
applications. To achieve this goal, a few diverse problems are
considered. The book is organized with adequate space dedicated for
the design and analysis of fractal apertures in waveguides,
conducting screens and cavities, microwave/millimeter wave
applications followed by detailed case-study problems to infuse
better insight and understanding of the subject. Finally, summaries
and suggestions are given for future work. Fractal geometries were
widely used in electromagnetics, specifically for antennas and
frequency selective surfaces (FSS). The self-similarity of fractal
geometry gives rise to a multiband response, whereas the
space-filling nature of the fractal geometries makes it an
efficient element in antenna and FSS unit cell miniaturization.
Until now, no efforts were made to study the behavior of these
fractal geometries for aperture coupling problems. The aperture
coupling problem is an important boundary value problem in
electromagnetics and used in waveguide filters and power dividers,
slotted ground planes, frequency selective surfaces and
metamaterials. The present book is intended to initiate a study of
the characteristics of fractal apertures in waveguides, conducting
screens and cavities. To perform a unified analysis of these
entirely dissimilar problems, the “generalized network
formulation of the aperture problems” by Mautz and Harrington was
extended to multiple-aperture geometry. The authors consider the
problem of coupling between two arbitrary regions coupled together
via multiple apertures of arbitrary shape. MATLAB codes were
developed for the problems and validated with the results available
in the literature as well as through simulations on ANSOFT's HFSS.
