Lossy Resonant Slot Coupling (Correspondence and Authors´ Reply)

The paper by Allen and Kino suggests a novel method of combating troublesome cut-off oscillations in periodic slow-wave structures. The idea is to couple loss periodically into the system through slots which are resonant at the center of the (narrow) oscillation range. The high Q of the slots will effectively decouple the loss in the operating range of the pass band.
