MS08: Modelling Simulation and Optimization in Electrical Engineering

  1. Idoia Cortes Garcia / Caren Tischendorf, Modelling, Simulation and Optimization in High Frequency Electromagnetics (MS08/1)
    Electrical engineering is an important technology for many recent social and industrial developments. It includes the investigation and application of electrical engineering, electronics and semiconductors. Therein, scientific challenges are often driven by industrial needs and are related to classical and new emerging topics of applied mathematics and scientific computing, i.e., modeling, simulation, optimization, uncertainty quantification, stochastics and data analysis. This minisymposium deals with simulation and optimization techniques for high frequency electromagnetics.

  4. Luis Bonilla / Vittorio Romano / Giovanni Mascali, Mathematical modeling of charge transport in graphene and low dimensional structures (MS08/4)
    The minisymposium will be concerned with the mathematical modeling and simulation of charge transport in graphene and other 2D materials and in structures, like double gate MOSFETs, nanoribbons and nano-wires, where the presence of confinement effects allows for the formal description of the carrier flow as that of a two dimensional or one dimensional electron gas. Graphene, thanks to its peculiar electrical properties and mechanical properties, is considered as one of the most promising materials for future electron devices. Lately, it has also been realized that, by increasing the miniaturization of devices, hot-spots are observed, that is zones with very high crystal temperature due to the release of energy by high energetic electrons. The effect is particularly relevant in materials with reduced dimensionality and confined structures.

    For these reasons, the minisymposium will foresee the discussion of the following arguments: ab initio calculations to furnish the correct band structures for the materials, e.g. doped graphene or graphene nanoribbons; thermal effects in the crystal lattice; rippling in suspended graphene as result of coupling between elasticity and Dirac fermions; in analytical properties of the Schrödinger equation; Monte Carlo simulations; Wigner transport equation; nonlinear dynamics in charge transport; numerical schemes for the charge carrier transport equation; fluid models deduced from the kinetic transport equations.
