Abstract:

The so-called extraordinary optical transmission (EOT) through metallic nanoholes has triggered extensive research in modern plasmonics and their applications in bio-sensing, imaging, etc. In this talk, I will present quantitative mathematical theory to understand scattering resonances that induce the EOT phenomenon in a series of metallic structures with sub-wavelength holes.

  • Seminar on Microlocal Analysis and Applications | Inverse scattering on non-compact manifolds with general metric

    Abstract:We consider a non-compact Riemannian manifold $M$ having ends equipped with asymptotically warped product metric. We allow any topology and metric for the finite part of $M$. As for the volume growth of each end, we assume any polynomial or exponential order. Studying the spectral properties of the Laplacian of $M$, we show that the S-matrix determines the manifold $M$. We can also in...
