Calculations concerning the electromagnetic effect of currents in a good conductor usually neglect the displacement current even at microwavw frequencies.
a) Assuming r = 1 and = 5.70 × 10 7 (S/m) for copper, cornpare the magnitude of the displacement current density with that of the conduction current density at 100 (GHz).
b) Write the governing differential equation for magnetic field intensity H in a source-free good conductor.
