Energy flow and the speed of electric field in DC circuit
... rewritten as p =σE2. It is generally accepted that the Poynting vector transmits electromagnetic energy in whole space. Indeed, this statement has certain limitations. As we know, the Poynting vector is expressed by S = E x H. E is the electric field intensity; H is the magnetic field intensity. Poy ...

Cone-jet Electrosprays, or Colloid Thrusters
... Q/K is reduced, the jet becomes thinner (as r∗ ∝ (Q/K)1/3 ),pthe droplets become smaller in the same proportion, and their specific charge increases as γK/Q. It would appear then that q/m can be indefinitely increased through flow reduction. Two phenomena have been identified, however, which limit ...
