Lightning Discharge and PCB Radiation

This lecture covers the phenomenon of lightning discharge, including cloud-to-ground lightning and the charge distribution in thunderstorm clouds. It also discusses the radiation from Printed Circuit Boards (PCBs), focusing on differential and common mode radiation, frequency spectrum, and current circulation in circuit loops. The evaluation of lightning overvoltages, direct and induced strikes, ground losses, and the use of shielding wires and surge arresters are explored. Experimental validation of lightning-induced currents and the impact of ground parameters on simulations are presented.
