M1-D FDTD methods for mobile interactive teaching and learning of wave propagation in transmission lines

This article presents the multiple 1D finite-difference time-domain (M1-D FDTD) methods for mobile interactive teaching and learning of wave propagation in transmission lines (TLs). Both the M1-D explicit FDTD method and the unconditionally stable M1-D fundamental alternating direction-implicit (FAD...
