From what I have gathered, spreading inductance of a plane is dimensionless (i.e. nH/sq) and not a function of the distance between two points, rather a function of aspect ratio of the plane - L x W. So, the size of the plane isn't what affects spreading inductance, but its shape does. Are these true statements? I want to make sure I understand this correctly.
