Abstract :
We report here a new behavioral feature of a narrow pulse transmitted on coplanar waveguide (CPW), putting the special stress on the effects caused by the packaging of such a waveguide. This feature occurs due to the unexpected simultaneous combination of a distortion in the guided main pulse and a production of delayed echo pulses. An explanation based on a new class of the dominant-mode power-leakage effect leads to a clear physical understanding of why such features necessarily appear
