Experimental demonstration of passive microwave pulse amplification via temporal Talbot effect [PDF]
Scientific Reports, 2023 The temporal Talbot effect is a passive phenomenon that occurs when a periodic signal propagates through a dispersive medium with a quadratic phase response that modulates the output pulse repetition rate based on the input period. As previously proposed,
