Metamaterials: Physics and Engineering Explorations
Preface. Contributors. PART I: DOUBLE-NEGATIVE (DNG) METAMATERIALS. SECTION I: THREE-DIMENSIONAL VOLUMETRIC DNG METAMATERIALS. CHAPTER 1: INTRODUCTION, HISTORY, AND SELECTED TOPICS IN FUNDAMENTAL… Expand
Wave propagation in media having negative permittivity and permeability.
TLDR
Wave propagation in a double negative (DNG) medium, i.e., a medium having negative permittivity and negative permeability, is studied both analytically and numerically and the DNG slab solution is used to critically examine the perfect lens concept suggested recently by Pendry. Expand
Design, fabrication, and testing of double negative metamaterials
The design, fabrication, and testing of several metamaterials that exhibit double negative (DNG) medium properties at X band frequencies are reported. DNG media are materials in which the… Expand
Metamaterial-Inspired Efficient Electrically Small Antennas
Planar two-dimensional (2D) and volumetric three-dimensional (3D) metamaterial-inspired efficient electrically-small antennas that are easy to design; are easy and inexpensive to build; and are easy… Expand
Application of double negative materials to increase the power radiated by electrically small antennas
The effect of surrounding an electrically small dipole antenna with a shell of double negative (DNG) material (/spl epsiv//sub r/<0 and /spl mu//sub r/<0) has been investigated both analytically and… Expand
Pulsed and CW Gaussian beam interactions with double negative metamaterial slabs.
TLDR
Gaussian beams that undergo total internal reflection from a DNG metamaterial slab are shown to experience a negative Goos-Hänchen (lateral) shift and several potential applications for these effects in the microwave and optical regimes are discussed. Expand
Metamaterial-based efficient electrically small antennas
A metamaterial paradigm for achieving an efficient, electrically small antenna is introduced. Spherical shells of ho- mogenous, isotropic negative permittivity (ENG) material are designed to create… Expand
Characterization of a volumetric metamaterial realization of an artificial magnetic conductor for antenna applications
The design, fabrication and measurement of a volumetric metamaterial realization of an artificial magnetic conductor (AMC) is presented. In contrast to most current realizations of AMCs, such as the… Expand
Exact solutions of the wave equation with complex source locations
New exact solutions of the homogeneous, free‐space wave equation are obtained. They originate from complex source points moving at a constant rate parallel to the real axis of propagation and,… Expand
Metamaterial-Inspired Engineering of Antennas
TLDR
Recent developments with this NFRP electrically small paradigm will be reviewed, including considerations of increased bandwidths, as well as multiband and multifunctional extensions. Expand
