![Q factor]] that the feed voltage is much smaller in relation to the standing wave. Since the antenna is fed at its resonant frequency, the input voltage is in phase with the current (blue bar), so the antenna presents a pure resistance to the feedline. The energy from the driving current provides the energy radiated as radio waves. In a receiving antenna the phase of the voltage at the transmission line would be reversed, since the receiver absorbs energy from the antenna.](https://commons.wikimedia.org/wiki/Special:FilePath/Dipole antenna standing waves animation 6 - 5fps.gif?width=200 "Q factor]] that the feed voltage is much smaller in relation to the standing wave.

The Fannie and John Hertz Foundation is an American non-profit organization that awards fellowships to Ph.D. students in the applied physical, biological and engineering sciences. The fellowship provides $250,000 of support over five years. The goal is for Fellows to be financially independent and free from traditional restrictions of their academic departments in order to promote innovation in collaboration with leading professors in the field. Through a rigorous application and interview process, the Hertz Foundation seeks to identify young scientists and engineers with the potential to change the world for the better and supports their research endeavors from an early stage. Fellowship recipients pledge to make their skills available to the United States in times of national emergency.
