Preface. Contributors. PART I: DOUBLE-NEGATIVE (DNG) METAMATERIALS. SECTION I: THREE-DIMENSIONAL VOLUMETRIC DNG METAMATERIALS. CHAPTER 1: INTRODUCTION, HISTORY, AND SELECTED TOPICS IN FUNDAMENTAL…

Wave propagation in media having negative permittivity and permeability.

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.

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…

Pulsed and CW Gaussian beam interactions with double negative metamaterial slabs.

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.

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,…

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…

A Review of the Scattering-Parameter Extraction Method with Clarification of Ambiguity Issues in Relation to Metamaterial Homogenization

The scattering-parameter extraction method of metamaterial homogenization is reviewed to show that the only ambiguity is that related to the choice of the branch of the complex logarithmic function…
