In this article, we demonstrate that in the case of a positive group velocity left-handed nonlinear (LH-NL) transmission line with series nonlinear capacitances, the spatial derivative of the voltage distribution satisfies the nonlinear Schrödinger (NLS) equation. Consequently, it will shown that a LH-NL transmission line with series varactors can be used to generate both bright and dark solito...

In this study, we propose a composite right/left-handed (CRLH) cuboid antenna operating in the very-high-frequency band. The proposed uses CRLH transmission-line structure for miniaturization, and left-handed component is implemented using interdigital capacitors meander lines. A three-dimensional was designed to increase parallel inductance by applying line side of structure. operates at 252.5...

A novel composite right/left handed transmission line (CRLH TL) is proposed, for the first time using the Wunderlich-shaped dentiform capacitor and meandered-line short-circuited stub inductor (SSI). The CRLH TL features a larger value of CL and in turn a lower resonance relative to the previous one employing an interdigital capacitor and an SSI. The unique feature of the CRLH TL is applied to ...

This paper presents the numerical modelling and simulation of a 2D vertical well tubular model excited by coaxial radiofrequency transmission line placed in its annular space for purpose downhole RF energy transmission. The study identifies mechanism losses due to coupling between steel tubing casing using resonance mode analysis. design left-handed artificial power is proposed minimize right-h...

We report terahertz metamaterial waveguides based on the concept of composite right/left-handed transmission-lines. The waveguides are implemented in a metal-insulator-metal geometry fabricated with spin-coated Benzocyclobutene and contact photolithography. Angle-resolved reflection spectroscopy shows strong resonant absorption features corresponding to both right-handed and left-handed (backwa...
