In summary, there are three steps in the FDTD computation: However, the position of the magnetic fields is on the faces of the box-shaped cells. The precise location of the electric fields is on the edges of the cube. It provides the segmentation of space into box-shaped cells that are small in comparison to the overall wavelength. Utilizing the FDTD method will divide both time and space into distinct segments. Those in the field consider it the easiest and most effective way to model the effects of electromagnetism on a specific object or material. In summary, it is the technique for the simulation of computational electromagnetism. Maxwell's equations are the basis for FDTD and describe the effect and behavior of electromagnetism. Note: James Clerk Maxwell's equations symbolize one of the most refined and aphoristic ways to state the fundamentals of magnetism and electricity. Throughout this process, the magnetic and electric fields are calculated everywhere within the computational domain and as a function of time beginning at t = 0. The FDTD method is a discrete approximation of James Clerk Maxwell's equations that numerically and simultaneously solve in both time and 3-dimensional space. It did not officially receive the FDTD method designation until 1980. To this day, many still refer to this method as Yee's method. Yee first introduced the numerical analysis technique we call the finite-difference time-domain method in 1966. We utilize this method to model computational electrodynamics or find approximate solutions to the associated system of differential equations. In this case, the technique or method in question is the finite-difference time-domain (FDTD). However, in the areas of electronics and science, there is always a method for that. In smartphone marketing, the saying is, "There's an App for that."
