Guest Editorial Frontiers in Computational Electromagnetics

Computational electromagnetics (CEM) seeks numerical solutions to practical engineering problems involving electromagnetic fields and waves and their interactions with materials and designed structures and systems. While physical measurement of electromagnetic fields is often expensive and impractical, CEM develops cost-effective and efficient simulation tools to analyze, design, and optimize real-world devices, structures, and systems. Advancements in CEM rely on those in mathematical representation of physical problems, numerical foundations of methods and algorithms, and computing hardware and software infrastructure. Indeed, CEM research and practice demand the seamless but also the most advanced combination of advancements in engineering, physics, mathematics, and computer science, holding immense potential for transformative impact. CEM is one of the most challenging areas of computational science and engineering due to the inherent complexity of electromagnetic problems. Unlike problems in other disciplines, electromagnetic problems are truly 3-D, volumetric, and vector-based and involve radiation and interaction at a distance.
