Reciprocity [Stand on Standards]

The April 2010 issue of the IEEE Antennas and Propagation Magazine contained two papers that discussed various aspects of the Reciprocity Theorem. Reference [1] referred to various defining statements from several sources (all of which were published prior to 1997 ) in relation to antennas and propagation. In particular, propagation across the land-sea boundary was revisited. Reference [2] directed a discussion about the circuit applications of reciprocity. Both papers discussed some of the statements used to define reciprocity.
