Inductance of Wide Trace over a Ground Plane

calculate the inductance of wide trace over a ground plane

Cross section of Wide Trace transmission line over a Ground Plane
Cross section of Wide Trace transmission line over a Ground Plane
w[m] width of the trace
h[m] height of the trace above ground
t[m] thickness of the trace
µr[ ] relative permeability of the medium
L/l[H/m] Inductance per unit length
 

NOTE: numbers are in scientific notation (e.g.: 1.427e-9 H = 1.1427·10-9 H = 1.427 nH)
