Mixed plasmons coupling for expanding the bandwidth of near-perfect absorption at visible frequencies.

TL;DR: Field distribution and dispersion relationship indicate that mixed surface plasmons (M-SPs) coupling is supported by M-SHA and TML, and the absorption band is proved to be dominated by M -SPs coupling.

Role of bianisotropy in negative permeability and left-handed metamaterials

TL;DR: In this article, the existence of bianisotropic effects in those materials is investigated, making use of an approximate model, and some unexplained properties of the electromagnetic-wave propagation through these media, revealed by closer inspection of previous numerical simulations and experimental work, are highlighted.

Metallic delay lenses

TL;DR: A metallic lens antenna is described in which the focussing action is obtained by a reduction of the phase velocity of radio waves passing through the lens rather than by increasing it as in the original metal plate lens.
