Transmission line approach of left-handed (LH) materials and microstrip implementation of an artificial LH transmission line
Christophe Caloz,Tatsuo Itoh +1 more
TL;DR: It is shown that, in this line, left-handedness can be achieved without losses over an unlimited bandwidth, from the cutoff of the resulting high-pass filter to infinity, with excellent agreement with theory.
Journal ArticleDOI
Application of double negative materials to increase the power radiated by electrically small antennas
TL;DR: In this paper, the effect of surrounding an electrically small dipole antenna with a shell of double negative (DNG) material has been investigated both analytically and numerically, and it is shown that a properly designed dipole-DNG shell combination increases the real power radiated by more than an order of magnitude over the corresponding free space case.
