Superhydrophobic behavior achieved from hydrophilic surfaces
The superhydrophobic behavior of a surface can be generally attributed to the combination of its chemical composition and microscale texture. The surface can be both hydrophobic and rough, and the rou...

Interplay between plastic deformations and optical properties of metal surfaces: A multiscale study
Plastic deformations and instabilities may significantly change the surface geometry at macro-, meso-, and nanoscales. Here we investigate an interplay of different plastic instabilities emerging in t...

We propose an efficient approach for tuning the transmission characteristics of metamaterials through a continuous adjustment of the lattice structure and confirm it experimentally in the microwave range. The concept is rather general and applicable to various metamaterials as long as the effective medium description is valid. The demonstrated continuous tuning of a metamaterial response is highly desirable for a number of emerging applications of metamaterials, including sensors, filters, and switches, realizable in a wide frequency range. ©2009 American Institute of Physics
