Series Reflection Free Port

For port $i$ to be reflection free in a series adaptor, we require

$$R_i = R_J(i) \isdef \sum_{i\neq j} R_i \protect$$ (F.44)

That is, the port's impedance must equal the series combination of the other port wave impedances at the junction. This result can be compared with that for the parallel junction in §F.2.2.
