XFDTD & FDTD

XFDTD Three dimensional full wave electromagnetic solver based on the Finite Difference Time Domain method (FDTD) FDTD Solves Maxwell’s equations in time domain Space is segmented into box-shaped “cell” Time is quantized into small steps which represent the time required for the field to travel from one cell to the next
