# Conductor skin depth
# Scope: Good-conductor electromagnetic skin depth at supplied permeability.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

resistivity = 0.0000000168 ohm*m
frequency = 100000 Hz
permeability = 0.0000012566370614 H/m

depth := sqrt(resistivity/(pi*frequency*permeability)) [mm]

check skin depth target: depth >= 0.1 mm

scenario alternative: resistivity = 1.344e-08 ohm*m
