=== Computing Far-Field Characteristics in FDTD ===
[[Image:FDTD_FF2.png|thumb|400px|EM.Tempo's Far Field Acceleration dialog.]]
Far fields are the asymptotic form the fields when r → ∞ or k<sub>0</sub>r >> 1. Under these assumptions, the fields propagate outward as transverse electromagnetic (TEM) waves:
