DESCRIPTION:Nanophotonics modelling for 21St century applications is becomi
 ng vital. The computational modeling provides a fundamental understanding 
 of the relying physics behind the operation of photonic devices. However\,
  computational modeling is still a challenge as some of the existing model
 ing techniques fail to capture the correct behavior of nano-photonic devic
 es. In this regard\, this talk will introduce an overview of the existing 
 computational modeling tools for analyzing photonic devices\, in general\,
  and highlighting their salient features and shortcomings. It is well know
 n that “plasmonics” plays a vital role now in localising the optical f
 ield beyond the diffraction limit and hence in integrated optics. Therefor
 e\, the talk will focus on plasmonics modeling issues and the failure of t
 he classical electromagnetic solvers to accurately characterize the nano-p
 lasmonic devices. Therefore\, new accurate and stable beam propagation met
 hod will be introduced for analyzing plasmonics in the classical regime. T
 he rigor of this approach is mainly because of relying on the finite eleme
 nts method and the twice faster Blocked Schur algorithm which can exactly 
 represent all the wide spectrum of radiation\, evanescent\, and surface mo
 des produced by the strong discontinuity between metal and its surrounding
 s. Moreover\, in merging quantum plasmonic devices\, it becomes essential 
 to introduce “Quantum Corrected Model (QCM)” in order to accurately mo
 del these devices\, and the basics of QCM will be also discussed.\n\nSpeak

 pplications is becoming vital. The computational modeling provides a funda

 now in localising the optical field beyond the diffraction limit and hence

 ing issues and the failure of the classical electromagnetic solvers to acc
 urately characterize the nano-plasmonic devices. Therefore\, new accurate
