The frequency-domain methods on mobile apps can also be extended for further research and applications beyond electromagnetics, such as optics (diffraction gratings, photonic crystals) [134][135][136], acoustics (phononic crystals, elastic, anisotropic and piezoelectric media) [137][138][139][140][141][142][143][144], circuits (geometrical [145][146][147][148], Rollett-based [149,150] and quasi-invariant stability [151][152][153], pole-zero [154][155][156], energy consideration [157][158][159]), etc. Apart from providing seamless interactive simulations and insightful visualizations, our educational mobile apps may be enhanced with artificial intelligence (AI) via innovative mobile intelligent tutoring systems (ITS).…”

This paper presents an overview and review of the fundamental implicit finite-difference time-domain (FDTD) schemes for computational electromagnetics (CEM) and educational mobile apps. The fundamental implicit FDTD schemes are unconditionally stable and feature the most concise update procedures with matrix-operator-free right-hand sides (RHS). We review the developments of fundamental implicit schemes, which are simpler and more efficient than all previous implicit schemes having RHS matrix operators. They constitute the basis of unification for many implicit schemes including classical ones, providing insights into their interrelations along with simplifications, concise updates and efficient implementations. Based on the fundamental implicit schemes, further developments can be carried out more conveniently. Being the core CEM on mobile apps, the multiple one-dimensional (M1-D) FDTD methods are also reviewed. To simulate multiple transmission lines, stubs and coupled transmission lines efficiently, the M1-D explicit FDTD method as well as the unconditionally stable M1-D fundamental alternating direction implicit (FADI) FDTD and coupled line (CL) FDTD methods are discussed. With the unconditional stability of FADI methods, the simulations are fast-forwardable with enhanced efficiency. This is very useful for quick concept illustrations or phenomena demonstrations during interactive teaching and learning. Besides time domain, many frequency-domain methods are well-suited for further developments of useful mobile apps as well.
