Q-Track CTO, Dr. Hans G. Schantz will presenting a Lunch-N-Learn seminar to the Joint Communications, Antennas & Propagation, and Microwave Theory and Techniques (JCAM) Chapter of the Huntsville Section of the IEEE this Wednesday, August 19, at 11:15 am to 12:45 pm. Lunch (Chicken Tenders) will be served, courtesy of his hosts at Technology Services Corporation (TSC) in Huntsville. Register here.
Dr. Schantz’s talk proposes a novel definition of near or reactive fields by reference to the electromagnetic Lagrangian and reviews basic concepts including energy velocity, energy flow, and impedance from a reactive perspective. Schelkunoff’s 1-D transmission line concept serves as a simple conceptual framework within which to understand the behavior and motion of energy in the context of opens, shorts, and other basic examples. Application of these concepts to the dipole fields reveal fundamental properties of small antennas including quality factor and gain limits. Finally, these ideas have practical applications in understanding the different behavior of electric and magnetic antennas, in determining indoor location, and elsewhere in physics.
