This lecture covers the ac-excitation of Josephson Junction currents, discussing the response to different excitation methods and the impact of capacitance. It explores the behavior of overdamped junctions under ac voltage excitation, emphasizing the time-dependent phase response and frequency mixing. The lecture also delves into the measurement techniques on industrial Josephson Junctions and the effects of thermal fluctuations on premature switching. Additionally, it explains the operation of SQUID in the voltage state, highlighting the challenges in measuring Imax and the behavior in the presence of screening. Overall, the lecture provides a comprehensive overview of the behavior of Josephson Junctions under ac excitation.
