Best Student Paper Award at NEMO2023

Jul Van den Broeck receive the Best Student Paper Award at the 2023 IEEE MTT-S International Conference on Numerical Electromagnetic and Multiphysics Modeling and Optimization (NEMO2023) for his paper “Solving the Fully Coupled Time-Dependent Maxwell-Dirac System: A Second-Order Accurate Numerical Scheme"

About NEMO'2023

NEMO is an annual focal event, founded by the IEEE MTT Society, on electromagnetic- and multiphysics-based computer-aided design (EM-CAD), rotating between Europe, North America and Asia. It aims to stimulate a broad exploration of "disruptive" technologies of EM-CAD in addition to traditional topics.

The 2023 edition was held on June 28 - 30, 2023 in Winnipeg, Canada.

About the paper topic

Owing to their increased carrier velocities, Dirac materials have become a promising option for the integration into nanoelectronics. However, without the aid of simulation software that is able to accurately describe the behavior of these materials, the fabrication of novel devices is extremely challenging. In this work, we present a second-order accurate, multiphysics solution method for the pertinent time-dependent Maxwell-Dirac equations. The numerical stencils of the separate equations are presented, leading to a novel stability criterion for the minimally coupled Dirac equation. Afterwards, the second-order accuracy is demonstrated via a numerical example, in which a Dirac particle is represented as a wave packet.
