Finite-Difference Time-Domain Simulation of Wave Propagation in Space-Time-Varying Media: Derivation of schemes, extended framework, and illustrative examples

Abstract: We present a comprehensive tutorial on the finite-difference time-domain (FDTD) modeling of space, time, and space-time-varying media, building upon our previous review by offering a ...
