IAS PROGRAM ON WAVE FUNCTIONAL MATERIALS
Finite Element Modeling of Non-self-adjoint Waveguide Problems
Prof Yuntian Chen, Associate Professor of Optical and Electronic Information, Huazhong University of Science and Technology
Date : 5 Dec 2016 (Monday)
Time : 11:00 am - 12:00 nn
Venue : IAS1038, 1/F, Lo Ka Chung Building, Lee Shau Kee Campus, HKUST

Abstract

The translation symmetry along the propagation direction of the waveguide can be used to reduce the dimensionality in waveguide modeling problems. Such dimensional reduction significantly saves the computational cost and has been used extensively in waveguides modeling. In contrast, if the waveguides contain anisotropic media, the dimensional reduction technique may potentially render the waveguide problem as a non-self-adjoint problem. In this work, the speaker and his research group study the conceptual consequences of the material anisotropy in waveguides and possible solutions to general non-self-adjoint waveguide problems using finite element method.

 

About the speaker

Dr Yuntian Chen obtained his Bachelor’s degree in Tianjin University in 2005, his MSc degree in Photonics in Zhejiang University and the Royal Institute of Technology in 2007 and his PhD degree in Technical University of Denmark (DTU) in 2010. Shortly after graduation, he joined the group of Prof Jesper Mørk at DTU as a Postdoctoral Fellow and worked on the project “Plasmon based light-emitting diode”. He is currently an Associate Professor in the Huazhong University of Science and Technology.
