Open publisher page 2 citations

Abstract

This paper presents the enhanced electromagnetics (EM) education using mobile apps that incorporate innovative computational electromagnetics (CEM) methods. The key features of CEM methods well-suited for educational mobile apps are highlighted, including small computing resources, real-time interactive, user-configurable and fast-forwardable simulations. These features can be realized using efficient multiple one-dimensional (M1-D) finite-difference time-domain (FDTD) methods, innovative models and unconditionally stable fundamental implicit FDTD schemes involving concise, simple and efficient update equations with matrix-operator-free right-hand sides. Besides teaching and learning, thorough online assessments and examination are discussed with EM question setting including intermediate workings of vector operations, integration, etc.
