Undergrad Antennas Course - Lecture 11 - Near field & Far field zones

This lecture is focused on examining the power density vector of an infinitesimal dipole antenna in its near-field and far-field zones. (This lecture is based on the following textbook: Antenna Theory: Analysis and Design, C. A. Balanis, 4th edition, Wiley, 2016. In 31:40, a picture is drawn which is based on a Figure in the Antennas textbook by Kraus and Marhefka, McGraw-Hill.)
