Using the Partial Wave Method for Wave Structure Calculation and the Conceptual Interpretation of Elastodynamic Guided Waves

open access: yesApplied Sciences, 2018
The partial-wave method takes advantage of the Christoffel equation’s generality to represent waves within a waveguide. More specifically, the partial-wave method is well known for its usefulness when calculating dispersion curves for multilayered ...

Superluminal plasmons with resonant gain in population inverted bilayer graphene

open access: yes, 2017
AB-stacked bilayer graphene with a tunable electronic bandgap in excess of the optical phonon energy presents an interesting active medium, and we consider such theoretical possibility in this work.

Acoustic Leaky-Wave antenna

open access: yes2014 8th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics, 2014
In the last years, the number of studies carried out in the field of acoustic metamaterials has significantly increased. In year 2009, our group proposed a concept of acoustic composite right/left hand transmission line (CRLH-TL) metamaterial, consisting of a waveguide periodically loaded with membranes along the duct, and transverse open channels ...
