He will focus on two approaches his department has pioneere d in the past years\, the plasmonic cloaking and the mantle cloaking techn iques\, respectively\, based on bulk plasmonic metamaterials and ultrathin metasurfaces. He will show the theoretical concepts at the basis of these approaches and the experimental results at radio-waves\, which represent the first experimental verification of cloaking for 3D free-standing objec ts. Professor Alu will also discuss advanced concepts\, such as the ultima te bounds on realizing ‘invisible sensors’\, the general bounds and po tentials of cloaking and invisibility on bandwidth and overall scattering reduction\, and ways to overcome these limitations using active\, non-Fost er cloaks.\n\nIntroduction to Anechoic Chambers\n\nBy Mr. Zhong Chen\, ETS -Lindgren\n\nThis presentation provides an overview of the RF/microwave ab sorbers and their use in the optimized designs of anechoic chambers. A bri ef theoretical background and measurement methods are introduced on the ab sorbers and chamber designs. Measurement techniques on the absorbers and c hambers are discussed\, including the free-space VSWR method. The free-spa ce VSWR is the most widely used method for measuring the performance of an anechoic chamber. Its test procedure and theory are introduced. Further d iscussions are provided on various chamber design considerations and the u se of absorbers to enhance the performances of an anechoic chamber.\n\nCol laborative Beamforming from Swarming UAS\n\nBy Professor Gregory Huff\, Te xas A&M University\n\nUnmanned aircraft systems (UAS)\, otherwise known as drones or UAVs\, have become indispensable tools in security\, entertainm ent\, and research but we are just beginning to understand their collectiv e capabilities in unstructured swarms and clusters. This presentation will focus on the development of MEDUSA\, which is a computer vision-assisted phased array controller that was engineered to study the behavior of unstr uctured volumetric arrays in morphing clusters. A review will be provided of the pioneering research into the development of experimental test-beds\ , analysis tools\, and reconfigurable antenna technologies developed to st udy the behavior of these unique systems-of-systems.\n\nSpeaker(s): \, \, \, \n\n11500 North MoPac Expressway\, Austin\, Texas\, United States\, 787 59 LOCATION:11500 North MoPac Expressway\, Austin\, Texas\, United States\, 78 759 ORGANIZER:alu@mail.utexas.edu SEQUENCE:3 SUMMARY:IEEE Central Texas EMC and MTT/AP Chapters Joint Antenna Workshop URL;VALUE=URI:https://events.vtools.ieee.org/m/40943 X-ALT-DESC:Description: <br /><h1>TECHNICAL PROGRAM</h1>\n<p><strong>&nbsp\ ;</strong></p>\n<p><strong>Please register for the event at Eventbrite at &nbsp\;https://www.eventbrite.com/e/ieee-central-texas-emcmttap-joint-chap ter-workshop-tickets-27218085025</strong></p>\n<p><strong>Cloaking and Inv isibility Using Metamaterials and Metasurfaces</strong></p>\n<p><strong><e m>By Professor Andrea </em></strong><strong><em>Al&ugrave\;\, University o f Texas at Austin</em></strong><br /> In this lecture\, Professor Alu will discuss his recent progress and research activity in using metamaterial c overs to suitably tailoring the scattering of passive objects\, drasticall y suppressing their overall detectability.
