Transmission Line Coupling Equations

This lecture covers the derivation of field-to-transmission line coupling equations, starting with the analysis methods and validity of the quasistatic and transmission line theories. It then delves into the differential mode and common mode currents, their significance on radiated emissions, and the electromagnetic radiation from elemental dipole antennas. The lecture also discusses the small electric and magnetic dipoles, their fields in near and far regions, and the wave impedance in free space. The session concludes with the transmission line theory assumptions, limitations, and the classical and generalized transmission line equations.
