![]() ![]() Gain a greater understanding of the application of the finite-difference time-domain. Learn more about the formulations associated with the finite-difference time-domain.Įlectrodynamics, quantum physics, electrostatics, thermodynamics, and Maxwell's equations. In the fields of science and electronics alike, there are always problems or equations that require solving. In smartphone marketing, the saying is, "There's an App for that." Throughout the advancement of these and similar areas of study or focus, there are methods in use for this precise purpose. However, in the areas 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 equations. Yee first introduced the numerical analysis technique we call the finite-difference time-domain method in 1966. To this day, many still refer to this method as Yee's method. It did not officially receive the FDTD method designation until 1980. 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. 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. ![]()
