This paper discusses two issues concerning the accuracy or electrical characterizations of Interconnect transmission lines, particularly in regard to a recently published paper. The error in the characteristic impedance may be reduced through an
In the above letter, the authors report measurements of the complex propagation constant y of a coplanar waveguide and the application of r to the determination of the characteristic impedance. The authors state that "the same information could, in
Recent theoretical developments have resulted in the rigorous definition of equivalent circuit parameters for non-TEM transmission lines. This summary provides a brief review of the theory and presents calculated and measured results illustrating the
