The phenomonon you are speaking of is the quasi-static assumption. B. =

estimates in his book that the maximum circuit dimension must be less =
than
the wavelength/10 or wavelength/30. This maximum circuit dimension would
be the equivalent electrical length. approx.=3D Er*Mechanical length... =

sure if this relates directly to the Td of the line.
Optimization of the lumped element models, and increasing degree of =
complexity
will extend the used of simplified models.
