Session Time & Room : 2C (Aug.22, 13:20-15:00) @E701
Type : Proposal of Minisymposium
Abstract : This mini-symposium presents numerical modeling, analysis and simulation using finite element method in the field of electromagnetism at various scales, from analyzing quantum mechanical effects to calculating the scattering of electromagnetic wave in free space. The Schrodinger-Poisson system of equations to calculate electron states in 3D hetero-structure will be discussed. Numerical modeling of display device will be presented and numerical analysis will be explored for microwave circuits. The electromagnetic vector wave scattering problem is solved to analyze the field characteristics in the presence of stealth platform. This mini-symposium also introduces several challenging issues in these applications and proposes their solutions.

Author(s) :
Woochan Lee (Incheon National University)
Abstract : The finite element method plays a significant role in the electromagnetic analysis of integrated circuits (IC) in electrical engineering. As IC structures constitute a very large-scale problem, the resources required for finite element modeling and analysis increase exponentially, making high-speed electromagnetic analysis an essential factor. This talk reviews recent trends in accelerating electromagnetic analysis, including the fundamental application of time- and frequency-domain finite element methods, high-speed techniques utilizing brick element characteristics, and parallel processing techniques.
[03728] Forced field continuity condition of object interface for the vector wave equation
Author(s) :
Hyesun Na (Yonsei University)
Abstract : Electromagnetic wave scattering problem is considered when perfect electric conductor is coated with several dielectric layers. Solving the scattering problem using finite element method requires huge number of degrees of freedom. Insufficient degrees of freedom may not be able to capture the information about abrupt changes in the interface. This work proposes to force a field continuity condition on the functional to overcome the difficulty.

URANCHIMEG DORLIGJAV (Yonsei university )
Abstract : In this work, we propose an algorithm to calculate electron density and space charge effect in 3D nanoscale device containing heterogeneous quantum dots. We begin by formulating the nonequilibrium Green’s function (NEGF) approach to calculate electron density and apply a nonlinear solver for Poisson equation using the finite element method.

Abstract : Modelling the hydrodynamics of charged colloids within ionic fluids is a challenging multi-physics problem. Rigid body particle motion is resisted by drag due to the viscosity of the fluid. Furthermore, ionic impurities give rise to electrical-double layers that can in turn induce flow of the solvent. In this paper, a moving mesh method for nano-rod electro-osmosis is introduced and applied to analyse particle trajectories in response to external electric fields.
