Wave Reflection on Lines (and Cables)If an open-wire transmission line or a cable is not terminated in its characteristic impedance Z0, some of the energy that reaches the distant end will be reflected. The reflected energy, in the form of a reflected wave, travels back toward the sending end. As it travels, it interferes with the oncoming initial wave that the source of signal energy is impressing at the sending end. The reflection and interference phenomena that occur can be studied mathematically or graphically.6 In the following discussions it will be assumed that the lines (or cables) are lossless. The lines will be either open circuited or short circuited at the distant end.
