The shunt impedance R sh relates P c to the accelerating voltage: P c = V 2 c R sh. The geometric shunt impedance, R sh/Q 0 (R/Q), can be recast as R sh/Q 0 = V 2 ω 0U. R/Q depends only on the cavity’s shape, and it should be maximized for a …
Webpatches in shunt connection. The following figure illustrates the layout. The reference planes are marked RP1 and RP2 in the above diagram. The analysis accuracy is best for high dielectric constants and for strip characteristic impedance values ≥ 50 Ω. The implemented model may consider conductor losses as well as dielectric losses.
