Electric field E r transverse to the current in a moving quasi-neutral plasma can (and should) be considered using Poisson equations and densities of volume charges emerging in the plasma. In the general case, E r becomes nonlocal; i.e., remote volume charge densities are not screene...
Electric field E r transverse to the current in a moving quasi-neutral plasma can (and should) be considered using Poisson equations and densities of volume charges emerging in the plasma. In the general case, E r becomes nonlocal; i.e., remote volume charge densities are not screened but...

In 1963 Ridley postulated that under certain bias conditions circuit elements exhibiting a current- or voltage-controlled negative differential resistance will separate into coexisting domains with different current densities or electric fields, respecti
where E is the electric field in V/m, ρ is the charge density and ∈0 is the permittivity of air. The electric potential (in volts), defined as the work done in bringing a unit of positive charge from infinity to that point, can be derived from Maxwell’s equation and is related ...
where q is the elementary charge; ni (ne), ji (je), and μi (μe) are the number density, the current density, and the mobility of ions (electrons), respectively; and E is the electric field. Equation (1) indicates that the electric wind is generated in the non-neutral region wher...
The former is often referred to as the ‘magnetic flux density’ or the ‘magnetic induction,’ while the latter is commonly described as the ‘magnetic field strength.’ In this book I will mostly refer to E and H as the ‘electric field strength’ and the ‘magnetic field strength,’ ...
In a certain region of space, the electric field is uniform. It can be proved that the volume charge density must be zero based on the Gauss's law. 点击查看答案 第10题 The author's assertions concerning the conditions that lead to the decay of the vacuum would be most weakened if whi...
