Finite-difference time-domain (FDTD) is a numerical simulation technique used in electromagnetics to solve Maxwell's equations. It discretizes the equations into finite differences in time and space, allowing for the simulation of electromagnetic wave propagation and interaction with materials and structures. FDTD is commonly used in modeling antennas, waveguides, radar systems, and other electromagnetic devices. It is a versatile and efficient method for analyzing complex electromagnetic problems in both time and frequency domains.
