Find the magnitude of the displacement current density in air at a frequency of 18GHz in frequency domain. Take electric field E as 4 units.
Calculate the frequency at which the conduction and displacement currents become equal with unity conductivity in a material of permittivity 2.
The ratio of conduction to displacement current density is referred to as
If the loss tangent is very less, then the material will be a
In good conductors, the electric and magnetic fields will be
