    Negative C lumped model Hyperlynx3D EM


      Dear Sirs, I drawed a structure with 6 capacitors (see file MultiCap.png in attach, please).

      After simulation (@ 10 Mhz, 500 Mhz and 1 Ghz), I select N-port PI Network with shunt RC in Lumped  Model.

      I notice that some capacitance values (even if they are very small) are negative.

      What that means?

      Thanks a lot for your support.
