Abstract: The three Pauli spin matrices ${\sigma _i}\left ( {i = 1,2,3} \right )$ occur in the mechanical, especially quantum mechanical, theory of rotation in three-dimensional space. The three spin matrix exponentials are here defined as exp $\left ( {{\sigma _i}x} \right )$, where $x$ is the independent variable. Transmission matrices can be expressed in terms of spin matrix exponentials, thereby permitting a more systematic treatment of transmission line circuits.

The counterpart to Eq. (16) is${\Gamma _1} = {\Gamma _2} = \Gamma$, which arises with symmetrical networks. In this case, the transmission coefficient and reflection coefficient vectors are orthogonal. See Leo Young, A theorem on lossless symmetrical networks, Trans. IRE CT-7, 75 (1960)
