Journal ArticleDOI
Wetting dynamics and evaporation of sessile droplets on nano-porous alumina surfaces
TL;DR: In this paper, an experimental investigation of wetting and evaporation of sessile droplets is presented on nano-porous alumina substrates having different pore distribution (uniform, random and linearly arranged) morphologies and pore sizes (70-120nm).
Journal ArticleDOI
Anisotropic Metamaterial Optical Fibers
TL;DR: Anisotropic metamaterials assembled into cylindrically symmetric geometries constitute light-guiding structures that support new kinds of exotic modes, such as photonic crystal fibers, which can confine light inside a hollow air core by Bragg scattering from a periodic array of holes.
Journal ArticleDOI
Anisotropic metamaterial optical fibers.
TL;DR: Internal physical structure can drastically modify the properties of waveguides: photonic crystal fibers are able to confine light inside a hollow air core by Bragg scattering from a periodic array of holes, while metamaterial loaded waveguide for microwaves can support propagation at frequencies well below cutoff.
Journal ArticleDOI
A class of circular waveguiding structures containing cylindrically anisotropic metamaterials: Applications from radio frequency/microwave to optical frequencies
TL;DR: In this paper, the authors investigated a class of circular waveguiding structures containing anisotropic metamaterials, and explored their potential benefits in applications from RF to optical frequencies.
Journal ArticleDOI
Pool boiling of water on nano-structured micro wires at sub-atmospheric conditions
TL;DR: In this paper, an experimental setup was designed and developed to investigate the pool boiling performance of water on (a) plain aluminum micro wire (99.999% pure) and (b) nano-porous alumina structured aluminum micro wires, both having diameter of 250µm, under sub-atmospheric pressure.
