On the basis of physical analyses, an improved physical-based design method that is especially suitable for high-power devices is developed. The proposed method overcomes the difficulties resulting from increased operating voltages and requirements for higher interaction impedance in high-power designs. It enables balancing of dispersion and interaction impedance, which is a flexible approach in addressing operational problems. Furthermore, the essential relationship between the proposed and the existing methods are revealed. A Ka-band folded waveguide TWT amplifier is designed and examined, thereby confirming that the new design method is effective and reliable.
