Notes: top

Equations hold for coaxial, stripline, and conical transmission lines. Diagram shows a coaxial line.

Equations hold for positive and negative polarity (negative polarity shown in diagram), but do not hold in the case of a positive polarity MITL (because of the layered flow resulting from emission from each of the feed cells). For the case of a positive polarity MITL, the self-limited impedance is ~Zo/2.

For the under-matched case, there are two solutions. This page calculates the solution with the most bound current.
