This lecture covers the emission of electromagnetic (EM) waves, starting with a reminder of Maxwell's equations and the properties of EM waves. It then explains the necessary conditions for EM wave emission, focusing on the role of alternating current in producing EM waves using LC circuits. The lecture also delves into the dynamics of charges and fields in LC circuits, illustrating how accelerating charges are essential for EM wave production. Additionally, it explores the relationship between inductance and capacitance in generating EM waves and concludes with a summary of key concepts related to EM wave emission.
