Hello,
Can someone tell me where the equations (you proposed on this website) to calculate the characteristic impedance of Microstrip come from?

They are based on what? Which formulas? How were they formulated (Which approach, which simplifications,....)?
Do you have any references to read (Videos, Books, ......) about it?
Best regards,
Jacques-Antoine Goormachtigh
