# Stripline impedance estimate
# Scope: Lossless transmission line from supplied per-length L and C; no stackup field solve.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

inductancePerLength = 250 nH/m
capacitancePerLength = 100 pF/m

impedance := sqrt(inductancePerLength/capacitancePerLength) [ohm]
speed := 1/sqrt(inductancePerLength*capacitancePerLength) [m/s]

check impedance target upper: impedance <= 55 ohm

scenario alternative: inductancePerLength = 200 nH/m
