Analysis Of a Modified Tunnelandder Slow wave Circuit

This article modified the Tunneladder circuit expecting to widen the bandwidth and hope to carry on its merits. In this modified Tunneladder circuit, 'forward-wave' was assumed. Cross-section resembling the idealized unmodified circuit of Tunneladder is analyzed. Through making the longitudinal electronic fields satisfying the boundary condition at one point along the boundary, the dispersing equation and interaction impedance expression of Tunnelplane was derived. Good accordance between theory and HFSS of dispersion characteristics of Tunnelplane is acquired.
