Several electric field soundings through stratiform clouds and convective regions of a mid-latitude mesoscale convective system, made with balloon-borne electric field meters and radiosondes, have been examined. All these soundings demonstrate the presence of fine structures in the electric field distribution, with characteristic spatial scales of irregularities ranging from hundreds to tens of...

Carbon nanotubes (CNT) allow easy entrance and passage of water [1] and are thus of interest for microfluidics. In electro-osmosis, charged double layers are set into motion by external electric fields. In recent simulations, electro-osmosis of water inside a CNT in the absence of free charges was observed and rationalized by invoking an electric-field-driven torque-vorticity conversion at orie...

Electricfield distributions measured using the Kerr effect cause a phase,shift between light components polarized parallel and perpendicular to the electric field, proportional to the magnitude sqyared of the electric field components in the plane perpendicdar to light propagation integrated over the light path length. One wishes to recover the electric field distribution from m4asurements of l...

Chiral 3D photonic crystals are an interesting subclass of 3D photonic crystals. For example, large complete 3D photonic bandgaps have been predicted for high-index-contrast silicon square-spiral structures; corresponding experiments using glancing-incidence deposition, interference lithography, or direct laser writing have been published. In addition to complete gaps or stop bands, theory also...
