It is shown that extraordinary light transmission of periodic subwavelength hole arrays, generally attributed to surface-plasmon resonances, is strongly influenced by the hole shape, and shape resonances of the rectangular holes play a dominant role.
Experiments on seismic metamaterials: molding surface waves.
For complex natural materials such as soils, this large-scale experiment was needed to show the practical feasibility of seismic metamaterials and to stress their importance for applications in civil engineering.

The effect of the aspect ratio of rectangular holes on the transmissivity of periodic arrays of subwavelength holes in optically thick metal films is investigated. The transmissivity is found to be…

Ultrabroadband elastic cloaking in thin plates.
A design for a cloak to control bending waves propagating in isotropic heterogeneous thin plates is proposed, achieved through homogenization of a multilayered concentric coating filled with piecewise constant isotropIC elastic material.

We report the design of a directive antenna using the electromagnetic resonances of a Fabry-Perot cavity. The Fabry-Perot cavity is made of a ground plane and a single metallic grid. The resonance is…
Morpho butterflies wings color modeled with lamellar grating theory.
An approach for converting reflection coefficients of any structure into colors, taking into account human color perception, is described, applied to the study of the colors reflected by Morpho rhetenor butterflies wings.
Photonic crystal lens: from negative refraction and negative index to negative permittivity and permeability.
It is shown that a given finite size photonic crystal can mimic a homogeneous material whose permittivity and permeability are negative and the vital role of the truncation of the crystal is paid to.
