Abstract :
Based on the generalized mode-analysis technique, a rigorous numerical model for simulating cold tests of millimeter-wave coupled-cavity slow-wave circuits is developed. This model provides not only the dispersion property but also the cold RF field distribution in the structure. The result is compared with that obtained by H.J. Curnow´s (1965) equivalent circuit, and good agreement is found. With appropriate modifications, the model can be used effectively as a design method for coupled-cavity TWTs (traveling-wave tubes).<>
