Abstract
Many of IAMCS people are well aware what KAUST is and has strong relations with this Saudi university. But virtually all IAMCS’ contacts at KAUST are at KAUST’s Division of Mathematical and Computer Sciences. This talk will introduce the most mathematical laboratory of KAUST’s Division of Physical Sciences and Engineering – Computational Electromagnetics Laboratory (CEML) and its main research directions. The second half of the talk will detail the author’s research at CEML, namely, development and implementation of exact absorbing boundary conditions (EACs). It’s well known that unbounded domain of interested must be truncated to a bounded computation domain for numerical solution of Maxwell’s equations using differential-equation-based solvers. The most well-known solutions to this problem are absorbing boundary conditions (ABCs) and perfectly matched layers (PMLs). However none of these methods provides a tool for estimating the error introduced in the final result and this error increases with the increasing length of the observation time. Being exact (mathematically rigorous) EACs are free from these disadvantages. This talk will detail derivation and numerical implementation of EACs.
