Revisiting Composite Right-/Left-Handed Transmission Lines and Symmetric Couplers

Coupled-Line Couplers Based on the Composite Right/Left-Handed (CRLH) Transmission Lines

Distributed Amplifiers with Composite Left/right-handed Transmission Lines

The use of so-called “composite left/right-handed transmission lines” in the design of distributed amplifiers is discussed using a simple model for the active device. The simplified analysis performed herein shows that it is possible to modify the frequency response of forward and reverse power gains, a significant development which could lead to innovative distributed amplifier designs. © 2006...

Coupled Lines from Filter to Composite Right / Left Handed - Cells

This paper studies the left-handed behavior in conventional 2-port coupled line networks. The propagation parameters of 12 periodic structures, each has a different coupled line configuration, have been derived and the left-handed bands have been determined. Two structures were fabricated and measured to confirm the composite right/left handed (CRLH) characteristics. Measurements and EM simulat...

Development of solitons in composite right- and left-handed transmission lines periodically loaded with Schottky varactors

The characteristics of composite rightand left-handed CRLH transmission lines periodically loaded with Schottky varactors are discussed in relation to the development of solitons. CRLH lines are highly dispersive and thus, when appropriately designed, compensate the effect of nonlinearity introduced by the Schottky varactors to support solitons. The reductive perturbation method applied to the ...

Properties of Envelope Pulses Developed in Coupled Nonlinear Composite Right- and Left-handed Transmission Lines

We investigate the properties of nonlinear envelope pulses developed in a coupled composite rightand left-handed (CRLH) transmission line with regularly spaced Schottky varactors. It is found that the dispersive distortion of the envelope pulses carried by each mode is well compensated by nonlinearity introduced by the varactors. In addition, we numerically observe that the collision of two non...
