Abstract :
We describe a novel slow-wave structure formed by a periodic array of rectangular rings interconnected by diagonal conductors. The sheet beam topology has the potential to significantly increase the output power of traveling-wave amplifiers at millimeter-wave frequencies and the small circuit period enables operation at relatively low voltages, far from the conditions for backward-wave oscillation. We will present measurements and simulations of the cold characteristics of the structure and analyses of mode competition and bandwidth optimization.
