Cloaking and Invisibility Using Metamaterials and Metasurfaces

By Professor Andrea Alù, University of Texas at Austin
In this lecture, Professor Alu will discuss his recent progress and research activity in using metamaterial covers to suitably tailoring the scattering of passive objects, drastically suppressing their overall detectability. He will focus on two approaches his department has pioneered in the past years, the plasmonic cloaking and the mantle cloaking techniques, 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 objects.  Professor Alu will also discuss advanced concepts, such as the ultimate bounds on realizing ‘invisible sensors’, the general bounds and potentials of cloaking and invisibility on bandwidth and overall scattering reduction, and ways to overcome these limitations using active, non-Foster cloaks.

Introduction to Anechoic Chambers

By Mr. Zhong Chen, ETS-Lindgren

This presentation provides an overview of the RF/microwave absorbers and their use in the optimized designs of anechoic chambers.  A brief theoretical background and measurement methods are introduced on the absorbers and chamber designs.  Measurement techniques on the absorbers and chambers are discussed, including the free-space VSWR method.  The free-space VSWR is the most widely used method for measuring the performance of an anechoic chamber.  Its test procedure and theory are introduced.  Further discussions are provided on various chamber design considerations and the use of absorbers to enhance the performances of an anechoic chamber.

Collaborative Beamforming from Swarming UAS

By Professor Gregory Huff, Texas A&M University

Unmanned aircraft systems (UAS), otherwise known as drones or UAVs, have become indispensable tools in security, entertainment, and research but we are just beginning to understand their collective 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 unstructured 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 study the behavior of these unique systems-of-systems.
