  • Novel Acceleration Structure Using Slot Resonance

    2010-12-6 · We have also noticed that resonant slots provide a very large amount of coupling between cells, around 30%. This is much larger than typical side-coupling cell designs. The increased coupling diminishes structure fabrication tolerances. Slot resonance coupling also introduces a sign change in the coupling between adjacent on-axis cells vs. side
