    IE3D Capacitor Simulation in Shunt RC model

    ruscino

      Dear Sirs, I simulate a simple capacitor with plates of 4x2 mm and 5um of dielectric (dielectric constant=3.8).

      The 2-port PI with Shunt RC and Shunt RC model give me a correct value of 54 pf but R is 22987 Ohm.

       

      I simulated the capacitor  from 10 MHz to 100 MHz frequency range.

      I tried to simulate the capacitor with different TanD(E).

      The R values between two capacitor plates are (@ 10 MHz):

      TanD(E)=0.05 R=5780 Ohm

      TanD(E)=0.001 R= 163380 Ohm

      TanD(E)=0 , so no dielectric loss , R=360000 Ohm

       

      Why R is so low? I expected a more high value.

      What is R in Shunt RC model?

       

      Thanks

      Ettore.
