We considered the propagation of a short pulse in the picosecond range in coupled lines with a ratio of phase velocities of anti-phase and in-phase waves of 3:1. We showed experimentally a special aspect in the interference of in-phase and anti-phase waves in such structures, which leads to the input pulse separation between three ports without a significant energy loss associated with the reflection from the input. The wave interference was found to lead to a change in the directional properties of the structures under consideration and a separation of the pulse spectral components between the ports.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
