The Available Power of a Matched Generator from the Measured Load Power in the Presence of Small Dissipation and Mismatch of the Connecting Network (Correspondence)

It is sometimes necessary to determine the available power of a matched generator in terms of the power dissipated in a load when the load is connected to the generator by means of a slightly mismatched 4-pole having small loss. (A piece of waveguide or short length of coaxial line could exemplify such a 4-poIe; the discontinuities at flanges or at connectors and supporting beads could give rise to the slight mismatch.)
