An attempt is made to give a brief expose of some modern works on linear network properties. The concepts treated are the following: passivity, stability, efficiency, and nonreciprocity; n… Expand

The isometric circles for the direct and inverse linear fractional transformations can be used for transformations of impedances and polarization ratios. In the Ioxodromic case an inversion is… Expand

Some invariant properties of partially polarized electromagnetic waves are studied geometrically. Transformations of the complex degree of correlation and the degree of polarization are studied in… Expand
