Density models for streamer discharges: beyond cylindrical symmetry and homogeneous media
cylindrical symmetry homogeneous media
2010/11/16
Streamer electrical discharges are often investigated with computer simulations of density models (also called drift-diffusion-reaction models). We review these models, detailing their physical found...
Gaussian beam diffraction in inhomogeneous media of cylindrical symmetry
Gaussian beam diffraction paraxial complex geometrical optics inhomogeneous media of cylindrical symmetry
2011/5/9
The method of paraxial complex geometrical optics (PCGO) is presented, which describes
Gaussian beam (GB) diffraction in smoothly inhomogeneous media of cylindrical symmetry,
including fibers. PCGO ...
Finite volume analysis of temperature effects induced by active MRI implants with cylindrical symmetry: 1. Properly working devices
temperature effects active MRI cylindrical symmetry
2010/3/1
The results show dangerous heating for the assumed "worst-case scenario" only for constructions not acceptable for vascular implants. Realistic devices are safe with respect to temperature increases. ...
