    en.wikipedia.org/wiki/Talk:Reflection_coefficient

    If you accept that the reflection coefficient is equivalent to the S11 scattering parameter of the load, and that Z0 is the impedance the load sees looking out of its port, i.e. the source impedance, then the formula as written contradicts the definition of S11 (see Scattering_parameters). S11 is defined as b1/a1; a1 is defined as (1/2) K1 (V1 ...

    Solution: divide one of the tall cells so that the row gets one rowspan=1 cell (and don't mind the eventual loss of text-centering). Then kill the border between them. Don't forget to fill the cell with nothing ({}). This being the only solution that correctly preserves the cell height, matching that of the reference seven row table.
