Resistance Matrices

In a device with n source terminals, the resistance relationship is expressed by an n x n matrix:

Or, more concisely:

V = RI

The entries of the resistance matrix are in Ohms.

Q3D Extractor computes partial resistances—that is, the resistance only of the specific part of the structure being modeled. The rest of the current loop is not considered. The total resistance of the loop is the sum of the partial resistances of each section of it.
