Near-Field MetaSteering – A Method for Complete Steering of the Beam of Any Fixed-Beam Antenna
Distinguished Professor Karu Esselle, FRSN, FIEEE, FIEAust
University of Technology Sydney (UTS), Australia
With two metasurfaces placed in close proximity to a fixed-beam antenna, it is now possible to steer the beam of any fixed-beam antenna with no modifications to the antenna itself. Antenna beam is steered to any direction withing a large conical volume, in azimuth and elevation, by independently rotating the two near-field metasurfaces. This is believed to be the only method in electromagnetics that can efficiently steer the beam of any antenna without tilting the antenna itself. Also known as Near-Field Risely Prism Method, this method has been applied by several academic and industry organisations to develop innovative beam-steering antenna systems. Wideband operation and high-power operation have been demonstrated. This keynote speech will review some existing antenna beam-steering methods and describe the state-of-the-art of this exciting new method with many advantages.
Biography
Prof. Karu Esselle is the Distinguished Professor in Electromagnetic and Antenna Engineering at University of Technology Sydney. He is Australia’s 2022 Professional Engineer of the Year, and the leader of the MetaSteerers Team that won Australia’s national 2023 Eureka Prize for Outstanding Science in Safeguarding Australia. Eureka Prizes are considered Oscars of Australian Science. Karu is the only person to receive both a Eureka Prize and the Professional Engineer of the Year Award. He is a Fellow of the Royal Society of New South Wales, IEEE and Engineers Australia. In the 24-month period to December 2023, ten new awards and prizes expanded Kau’s portfolio of Research Excellence accolades. These include the most prestigious Space award in Australia – the “Winner of Winners” Excellence Award – as well as the Academic of Year Award at the 2022 Australian Space Awards, 2022 Chancellor’s Medal, both the Excellence Award and the Academic of the Year Award at 2021 Australian Defence Industry Awards, and 2019 Motohisa Kanda Award (from IEEE USA) for the most cited paper in IEEE Transactions on EMC in the past five years.
