4 AristotlePagaltzis 6 # The cross section of the first FresnelZone is circular. Subsequent FresnelZone~s are annular in cross section, and concentric with the first.
7 # Odd-numbered FresnelZone~s have relatively intense field strengths, whereas even numbered FresnelZone~s are nulls.
8 # FresnelZone~s result from diffraction by the circular aperture. (188)
