Mobile Apps, Online Assessments and Examination for Electromagnetics Education

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.
