Calculating the electrical flux generated by a wire intecon

[carbon9]

Dear all,

How can I calculate the electrical flux generated by a silicon interconnect wire provided that I know the 3-D charge distribution (rho(r)) in a 3-D wire interconnect as shown below?

I'll use flux to calculate the parasitc inductance L=d(flux)/d(I))

Regards,

In your above equation, the numerator term "d(flux)" is the magnetic flux, not the electrical flux!

How stupid i am!)

L=magnetic flux/current, right. So, how can I calculate the magnetic flux from charge density rho(r)? Note that I do not have any time dependent variables. I only have time independent rho(r), Veff(r) and I.

Regards and thanks Erikl.

I think this is not the right method to calculate L. In order to calculate L via
L = d(mag.flux)/dI or from L = -Ui / (dI/dt) you need to consider self-induction behaviour, and this is not possible without time-dependency. If you need L to be calculated from static values, you must calculate it from pure physical (geometric and material-dependent) values. And then charge density is of no use.
