Extraction of embedded dispersion characteristics

A de-embedding method is presented which allows to extract the dispersion characteristics of embedded periodic waveguiding structures. It is shown that the only required reference standard is a Thru dummy. Except symmetry, no further requirements on the dummy are requested. Particularly, the Thru does not need to possess a certain network topology, like T or π-shaped network. Furthermore, no equivalent circuit needs to be assumed. By adding an additional Line standard S-parameters may also be determined.
