DESCRIPTION:We will be hosting a talk by Dr. Salah Obayya on Computational 
 Nanophotonics: Basics\, Challenges and Future Perspectives.\n\nAbstract be
 low:\n\nNanophotonics modelling for 21st century applications is becoming 
 vital. The computational modeling provides a fundamental understanding of 
 the relying physics behind the operation of photonic devices. However\, co
 mputational modeling is still a challenge as some of the existing modeling
  techniques fail to capture the correct behavior of nano-photonic devices.
  In this regard\, this talk will introduce an overview of the existing com
 putational modeling tools for analyzing photonic devices\, in general\, an
 d highlighting their salient features and shortcomings. It is well known t
 hat “plasmonics” plays a vital role now in localising the optical fiel
 d beyond the diffraction limit and hence in integrated optics. Therefore\,
  the talk will focus on plasmonics modeling issues and the failure of the 
 classical electromagnetic solvers to accurately characterize the nano-plas
 monic devices. Therefore\, new accurate and stable beam propagation method
  will be introduced for analyzing plasmonics in the classical regime. The 
 rigor of this approach is mainly because of relying on the finite elements
  method and the twice faster Blocked Schur algorithm which can exactly rep
 resent all the wide spectrum of radiation\, evanescent\, and surface modes
  produced by the strong discontinuity between metal and its surroundings. 
 Moreover\, in merging quantum plasmonic devices\, it becomes essential to 
 introduce “Quantum Corrected Model (QCM)” in order to accurately model
  these devices\, and the basics of QCM will be also discussed.\n\nVirtual:
