Hi Dr. Leigh-Smith. I have a question: the formula for the effective dielectric constant may be used for any width of the superior conductor or is only applicable for w very small (in the limit to 0)? Thanks alot.
Thank you so much for organizing it, it really helped me a lot. ;) But shouldn't there be a radical sign to the ee (effective permittivity) of the denominator in the Z0 formula when w/d
Hi! No, the characteristic impedance does not depend on the length of the line. That said, the definition of characteristic impedance assumes that the length of the line is large relative to a wavelength (so that propagating modes are the primary method of energy transmission).
