WWB13: Retrodirectivity

Posted on December 21, 2018 Written by Gregory Durgin

In this lecture, we discuss the origins of retrodirectivity, starting with the Van Atta array and its use as radar chaff.  We then demonstrate how to use these systems in communications links.  Part of the Shenzhen lecture series on wireless without batteries.
