Cst shunt impedance
Webwhile the shunt element of the T-equivalent is Z 12. If βl< π/2, the series elements have a positive reactance (inductors), while the shunt element has a negative reactance (capacitor). We thus have the equivalent circuit shown in Figure 1a, where Now assume a short length of line (say βl 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.

In accelerator physics, shunt impedance is a measure of the strength with which an eigenmode of a resonant radio frequency structure (e.g., in a microwave cavity) interacts with charged particles on a given straight line, typically along the axis of rotational symmetry. If not specified further, the term is likely to refer to longitudinal effective shunt impedance.
