DESCRIPTION:Abstract: In the history of Antenna Engineering\, there has bee
 n only one universal method to steer the beam of any fixed-beam antenna. T
 hat’s physically tilting the antenna. This method has been implemented i
 n many commercial antenna systems using motorised mechanical tilting and r
 otating systems. Now there is another way: Near-Field Meta-Steering\, in w
 hich two planar phase-gradient metasurfaces (MS) are placed very close to 
 the fixed-beam antenna\, in its near field\, and are rotated independently
 . This way\, the beam of the antenna can be steered over a large range of 
 zenith angles and complete azimuth range of 3600\, without tilting or rota
 ting the antenna. In fact\, no part of the system is tilted.\n\nA Meta-Ste
 ering antenna system is only slightly taller than the antenna itself. Lack
  of tilting means it is much shorter than conventional tilting antennas. I
 n the future\, one electronically reconfigurable near-field metasurface ma
 y provide 2D beam steering without any mechanical rotation.\n\nSince this 
 method was introduced in the seminal paper in 2017\, together with the Nea
 r-Field Phase Transformation concept\, it has been applied by many industr
 y and academic researchers across the globe to develop novel antenna syste
 ms\, and to steer the beam of all types of fixed-beam antennas\, e.g. Fabr
 y-Perot/resonant cavity antennas\, reflector (dish) antennas\, metasurface
  antennas\, slot arrays\, holographic antennas\, and even some end-fire an
 tennas\, to name a few. Several different types of metasurfaces have been 
 developed\, e.g. standard printed-circuit-board type\, all dielectric\, al
 l metal\, hybrid and 3D-printed\, and some research outcomes have led to n
 ational prizes and awards. This distinguished lecture will review the rese
 arch conducted by the speaker’s team as well as others in this modern an
 d growing area.\n\nSpeaker Bio: Karu Esselle\, FRSN\, FIEEE\, FIEAust\, is
  Distinguished Professor in Electromagnetic and Antenna Engineering at Uni

 a Eureka Prize and the Professional Engineer of the Year Award.\n\nKaru is

 s in USA\, Europe and Australia. A distinguished lecturer himself\, from 2
 018 to 2020 Karu chaired the Distinguished Lecturer Program Committee of t

 ommittees of this IEEE society. In addition\, Karu has been a Senior Edito
 r of IEEE Access and an Associate Editor of many international journals in
 cluding IEEE Transactions on Antennas Propagation\, IEEE Antennas and Prop
 agation Magazine\, IEEE Access and IET MAP. He was Director of WiMed Resea
