inductance of a rectangular loop

Hello,

how can I calculate the inductance of a rectangular loop with a rectangular wire?
I need the inducatnace in dependence of s1, s2, t and w: L=f(s1,s2,t,w)

s1: Rectangular side1
s2: Rectangular side2
w : Wire width
t : Wire thickness

Thx.
Does someone know a forumula for a rectangle and not a square? (s1 != s2)

I think that with good approximation the inductance is function of the perimeter of the polygon.
In your case just transform the rectangle in a square with the same perimeter and use the formula provided.
