The finite-difference time-domain (FDTD) method is a full-wave numerical method that directly discretizes the Maxwell's equations in the time-domain partial differential form. The Chinese American K.S. Yee developed the Yee discretizing scheme in the 1960s, by replacing the partial differential ...
As the name indicates, the method solves Maxwell's equations in time domain in three-dimensional space, allowing straightforward simulation of general, complex electromagnetic and photonic devices with a great degree of detail. Starting from the differential form of the equations, both time- and ...

of electronics and science, there is always a method for that. In this case, the technique or method in question is the finite-difference time-domain (FDTD). We utilize this method to model computational electrodynamics or find approximate solutions to the associated system of differential ...
This chapter reviews key elements of the theoretical foundation and numerical implementation of finite-difference time-domain (FDTD) solutions of Maxwell's equations. FDTD and related space-grid time-domain techniques are direct solution methods for Maxwell's curl equations. These methods employ no pot...
We compare Yee's finite-difference time-domain (FDTD) and symmetric condensed node transmission-line matrix (SCN-TLM) solutions for a cavity containing a metallic fin. Differential equation-based numerical methods are known to produce inaccurate results for this type of problem due to the rapid sp...
The following sections present the mathematical foundation for numerical solution of partial differential equations. Developing a numerical implementation of the time-domain solution with staggered-grid finite-difference approximation is also proposed for simulating electromagnetic wave propagation in 2-D media...
