Generating localized waves from independently addressable pulse driven arrays

Abstract

After a brief historical perspective on the origins and developments of space-time coupled solutions of the wave equation, the so-called localized waves (LWs), my presentation will emphasize how they can be and have been launched from independently addressable pulse driven (IAPD) arrays. These IAPD arrays are characterized by each element having the possibility to be driven with an individualized time domain waveform. Several acoustic and electromagnetic LW solutions, the IAPD arrays than can launch them, and the near-field and extended far-field region behaviors characterizing the localized beams launched by them, as well as the experiments that have verified these effects, will be discussed.
