DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Inverse/5/">
 Wave Interaction with Subwavelength Resonators</a>\nby Habib Ammari (ETH Z
 ürich) as part of International Zoom Inverse Problems Seminar\, UC Irvine
 \n\n\nAbstract\nIn this lecture\, the speaker reviews recent results on su
 bwavelength resonances. His main focus is on developing a mathematical and
  computational framework for their analysis. By characterizing and exploit
 ing subwavelength resonances in a variety of situations\, he proposes a ma
 thematical explanation for super-focusing of waves\, double-negative metam
 aterials\, Dirac singularities in honeycomb subwavelength structures\, and
  topologically protected defect modes at the subwavelength scale. He also 
 describes a new resonance approach for modelling the cochlea which predict
 s the existence of a travelling wave in the acoustic pressure in the cochl
 ea fluid and offers a basis for the tonotopic map.\n
