The increased awareness of complex media\, both naturally occurring and artificially con structed\, which has been stimulated by the debut of metamaterials\, has e nabled paradigm shifts in terms of our understanding of how devices and sy stems operate and our expectations of their performance characteristics. T hese shifts include the trends of miniaturization\, enhanced performance ( total radiated power\, bandwidth and directivity)\, reconfigurability and multifunctionality. New techniques have been developed that are truly begi nning to impact practical realizations and their applications.\n\nA variet y of metamaterial-inspired\, near-field resonant parasitic (NFRP)\, electr ically small antennas have been developed that exhibit multifunctional per formance\, enhanced bandwidths\, and higher directivities. Their engineeri ng is achieved by combining multiple NFRP elements with simple driven radi ators. Higher directivity is obtained by simultaneously exciting balanced electric and magnetic NFRP elements\, leading\, for example\, to endfire a nd broadside radiating Huygens dipole antennas (HDAs). Enhanced bandwidths and loss mitigation\, as well as wireless power transfer capabilities\, h ave been achieved by augmenting the HDAs with non-Foster (active) and rect ifying (rectenna) elements. A variety of HDAs have been fabricated and tes ted to confirm their attractive performance characteristics\; they will be reviewed briefly. Most recently\, both beam steerable linear arrays of HD As and higher-order multipole single-port antennas have been demonstrated to be in good agreement with their analytical and numerical predictions. T hese Huygens dipole antenna arrays (HDAAs) and Huygens multipole antennas (HMAs) will also be described. The potential of the HDAs\, HDAAs and HMAs for the much anticipated NextG electromagnetic ecosystems and associated I oT applications will be stressed throughout my presentation.\n\nVirtual: h ttps://events.vtools.ieee.org/m/313539 LOCATION:Virtual: https://events.vtools.ieee.org/m/313539 ORGANIZER:alex.mh.wong@cityu.edu.hk SEQUENCE:8 SUMMARY:Seminar:The Physics and Engineering of Metamaterial-inspired Electr ically Small Directive Antennas and Their NextG Applications URL;VALUE=URI:https://events.vtools.ieee.org/m/313539 X-ALT-DESC:Description: <br /><p><strong><span style="color: #34495e\; font -size: 18pt\;">Seminar</span></strong></p>\n<p><span style="font-size: 18p t\; color: #3598db\;"><strong>The Physics and Engineering of Metamaterial- inspired Electrically Small Directive Antennas and Their NextG Application s&nbsp\;</strong></span></p>\n<p><strong>Prof. Richard W.
