Characteristics of coplanar transmission lines on multilayer substrate
s expressed in analytic formulas have been obtained using conformal ma
pping. The accuracy of these formulas has been verified experimentally
on a variety of coplanar transmission lines using differential electr
o-optic (DEOS) sampling, For coplanar waveguides, the theory differs f
rom the experiment by less than 3%; for coplanar striplines, the diffe
rences are less than 6%.
