Interdigital Capacitor - Visualize and Analyze
This example shows you how to create, visualize, and analyze an interdigital capacitor.
Create an interdigital capacitor with default properties.
capacitor = interdigitalCapacitor
capacitor = interdigitalCapacitor with properties: NumFingers: 4 FingerLength: 0.0137 FingerWidth: 3.1600e-04 FingerSpacing: 3.0000e-04 FingerEdgeGap: 3.4100e-04 TerminalStripWidth: 5.0000e-04 PortLineWidth: 0.0019 PortLineLength: 0.0030 Height: 7.8700e-04 GroundPlaneWidth: 0.0030 Substrate: [1x1 dielectric] Conductor: [1x1 metal] SolverType: 'MoM' IsShielded: 0
View the capacitor.
show(capacitor)
Plot the charge distribution at 5 GHz.
charge(capacitor, 5e9)
Plot the current distribution at 5 GHz.
figure current(capacitor, 5e9)
Calculate and plot the s-parameters.
spar = sparameters(capacitor,linspace(1e9,10e9,30)); rfplot(spar)
