The characteristics of a two-dimensional (2D) left-handed traveling-wave field-effect transistor, which is two 2D composite rightand left-handed (CRLH) transmission lines with both passive and active couplings, are discussed for generating non-attenuated waves having left-handedness in 2D. In this study, the design criteria for wave amplification are described, and the results from numerical ca...

We report the true left-handed transmission of a composite metamaterial (CMM) consisting of periodically stacked split-ring resonator (SRR) and wire elements. The negative permeability (m < 0) gap is demonstrated explicitly by comparing SRR and closed-ring resonator structures. We confirm experimentally that the plasma cut-off frequency of the CMM is determined by the combined dielectric respon...

We study analytically and numerically the impact of second-neighbor interactions on propagation an initial wave-packet through a coupled nonlinear left-handed transmission line. start with detailed analysis dispersion curve group velocity. then use quasi-discrete approximation respect to long wavelength transverse perturbations reduce discrete model lattice Schrödinger equation. A product veloc...
