Finite-Difference Time-Domain (FDTD)

Finite-Difference Time-Domain (FDTD) is a computational method used to simulate how electromagnetic waves, like light or radio signals, travel through different materials. It works by dividing space into small grid-like parts and calculating how waves change over tiny time steps. This step-by-step process models the behavior of waves as they interact with objects, helping researchers analyze and design antennas, circuits, or optical devices without physical experiments. FDTD is valued for its accuracy and ability to handle complex, real-world scenarios involving electromagnetic phenomena.
