A Note to Show How an Alternative Spherical Mode Normalization Simplifies the Relationship Between Transmitting and Receiving Characteristics
Author: Doren W. Hess
In this paper we show how a modification in the choice of mode normalization changes the pair-wise transmitting-receiving conversion to a one-to-one equality for a reciprocal antenna... This change affords us greater simplicity and the opportunity to avoid confusion when manipulating the scattering coefficients. For this relation to hold, there is a useful convention defining two fiducial coordinate systems for the antenna – one a transmitting and the other a receiving coordinate system.
