Three-Dimensional Metallic Microstructures Fabricated by Soft Lithography and Microelectrodeposition
Soft lithography offers a convenient set of methods for the transfer of patterns to planar and nonplanar substrates. Microelectrodeposition can transform thin metal patterns into self-supporting microstructures, weld components together, and strengthen microstructures after deformations. Together, soft lithography and electrochemistry provide synergistic technologies and the basis for a strateg...
متن کاملChiral three-dimensional isotropic lattices with negative Poisson’s ratio
Chiral three-dimensional isotropic cubic lattices with rigid cubical nodules and multiple deformable ribs are developed and analyzed via finite element analysis. The lattices exhibit geometry dependent Poisson’s ratio that can be tuned to negative values. Poisson’s ratio decreases from positive to negative values as the number of cells increases. Isotropy is obtained by adjustment of aspect rat...

متن کاملStationary vortices in three - dimensional
An existence theorem for localised stationary vortex solutions in an external shear ow is proved for three-dimensional quasigeostrophic ow in an unbounded domain. The external ow is a linear shear ow whose strength varies linearly with height. The ow conserves an in nite family of Casimir integrals. Flows that have the same value of all Casimir integrals are called isovortical ows, and the pote...
متن کاملOptical properties of isotropic chiral media
A review is given of the optical properties of isotropic chiral media, based on the symmetrized constitutive relations of Condon. The review includes discussion of wave propagation in chiral media, and derivation of the reflection and transmission amplitudes of an isotropic optically active medium, and of a layer resting on a substrate. Boundary conditions and energy conservation relations are ...
