WebIntroduction. Meep implements the finite-difference time-domain ( FDTD) method for computational electromagnetics. This is a widely used technique in which space is divided into a discrete grid and the fields are evolved in time using discrete time steps — as the grid and the time steps are made finer and finer, this becomes a closer and ...
