I've just extracted the RLGC matrices for 5 coupled
striplines using Apsimtech RLGC.
As expected, the diagonal elements of the capacitive matrix are
positive capacitance values. All the off-diagonal elements are
negative EXCEPT one. Is this correct. It has been a while since I've
thought about this, but I was under the impression the capacitive
off diag element were all negative. Anyone know for sure ??
The element in column 1 row 5 is the one I question:
3.1600e-15
-4.9360e-16 3.2540e-15
-2.0080e-17 -4.8990e-16 3.2540e-15
-1.3380e-18 -1.9820e-17 -4.8990e-16 3.2540e-15
3.1280e-20 -1.3380e-18 -2.0080e-17 -4.9360e-16 3.1600e-15
