The paper introduces a new, computationally inexpensive, real-time method of simulation of clouds for dynamic particle-based cloud rendering. The method covers such phenomena as atmospheric fronts, stable and unstable balance, thunderstorms, simplified simulation of middle and high clouds, correlation between wind and clouds and even tornadoes. The simulation is based on several simple numeric ...
An all-dielectric semispherical lens with functions in shaping 3D wave-propagation paths is proposed and experimentally verified. When radiation sources are placed in the central region, the lens behaves as a magnifying device to resolve the sources in subwavelength scale; while when the electromagnetic waves impinge on the semispherical lens from outside, they will be guided spirally inward.
The transformation properties of the single complex quantity, introduced by Green and Wolf to describe the electromagnetic field, are investigated and the physical energy-momentum tensor of this field is derived in terms of the scalar theory. In particular, it is found that the energy density, as defined in the previous paper, is identical with that given by the physical energy-momentum tensor ...
