FDTD (Finite-Difference Time-Domain)

The Finite-Difference Time-Domain (FDTD) method is a computational technique used to simulate how electromagnetic waves, like light or radio signals, interact with objects and environments. It breaks down space and time into small, discrete steps, then calculates how electric and magnetic fields evolve each step based on Maxwell’s equations. This approach allows researchers and engineers to predict how waves will behave in complex scenarios, such as designing antennas, radar systems, or optical devices, providing detailed insights into wave interactions without needing physical prototypes.
