It is expected this formalism will clarify and extend matrix approaches to the description of this effect presented by others and will result in component loss characterization methods that are independent of the launch conditions chosen to make the characterization. The report shows that a reduced-dimension transfer matrix can be defined in terms of a rectangular matrix transformation from the full-dimension mode space to a reduce-dimension space and its pseudo-inverse. Further, it shows that the reduced-dimension space need not be a conventional mode-block partition. The report concludes that valid reduce-dimension representation should be attainable directly from vectorization of the near -field patterns without first developing the mode distribution.
