Module embedded 

Embedded microstrip impedance calculator.

An embedded (buried) microstrip is a surface microstrip covered by a dielectric overlay. The burial reduces both Zo and Er_eff compared to a surface microstrip.

Reference: Brooks, “Signal Integrity Issues and Printed Circuit Board Design”.

Z0_embedded = Z0_surface × (1 − exp(−2 × cover_height / height)) Er_eff_embedded = Er − (Er − Er_eff_surface) × exp(−2 × cover_height / height)
