“…With the recent wide availability of mobile devices, such kind of software could be extended for these handheld devices such as pads and phones. This is in line with our previous efforts to enhance teaching and learning of EM topics on microwave transmission line circuits [7], [8] and polarization [9], [10] by leveraging on the affordances of mobile devices. Compared to computers, mobile devices provide more effective touch-based interactivity and more importantly, they allow seamless teaching and learning anytime, anywhere.…”

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.

In this article, mobile teaching and learning of coupled line structures using multiple one-dimensional coupled line finite-difference time-domain (M1-D CL-FDTD) method are presented. The formulation of M1-D CL-FDTD method applicable for coupled line structures is provided. The method bypasses the more computationally intensive full-wave 3-D method and it is well-suited for implementation on mobile devices. Several mobile apps are developed to provide interactive visualization of EM wave propagation in coupled line structures. Such visualization allows the underlying resonating and coupling mechanisms to be elucidated clearly and improves students' understanding of coupled line theories. Mobile teaching and learning of various coupled line structures including coupled transmission lines, coupled line bandpass filter, directional coupler and branch line coupler are demonstrated and discussed.
