Antenna Simulation with XFDTD Dan Yi September 17, 2004

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
