Negative admittance in electric current simulation

Please login with a confirmed email address before reporting spam

Hello,

I'm trying to simulate electrical contact through oxided metal, and i use the contact impedance boundary condition as the properties of oxided layer. and i use both direct and iterative solver. however, the results came back showing that the admittance is negative at some frequency range. it doesn't make sense.

Anyone help me.

kind regards.
