In a good conductor the phase relation between the tangential components of electric field E_t and the magnetic field H_t is as follows

A two - wire transmission line of characteristic impedance $$Z_0$$ is connected to a load of impedance $${Z_L}({Z_L}\, \ne \,\,{Z_0})$$. Impedance matching cannot be achieved with

Vector potential is a vector

On either side of a charge-free interface between two media,
