A differential transmission line using a negative permittivity metamaterial is proposed with the intrinsic characteristic of wideband common-mode suppression. Based on the transmission line theory, a dispersion diagram is derived from the corresponding equivalent circuit model. It manifests that in the structure, the differential mode can propagate at all frequencies, while the common mode can only...
In this paper the most relevant applications derived from dispersion and impedance engineering in resonant type metamaterial transmission lines are highlighted. Essentially, this includes enhanced bandwidth components and dual-band components. Due to the small electrical size of the considered metamaterial resonators, size reduction is also obtained. We will provide some recent results obtained by...
A novel topology for the composite right/left-handed transmission line (CRLH TL) is presented. This type of CRLH TLs has the advantage of exhibiting an all-pass behavior and a frequency-independent characteristic impedance, in the so-called balanced case. Moreover, it presents a larger group velocity than its conventional counterpart, thereby allowing for wider bandwidth operation. This letter investigates...
