We report a numeric.l.method to anal.ze the frac.al.c.arac.eristic. of far-fiel. diffrac.ion patterns for two-dimensional.Thue-Morse (2-D TM) struc.ures. The far-fiel. diffrac.ion patterns of the 2-D TM struc.ures c.n be obtained by the numeric.l.method, and they have a good agreement with the experimental.ones. The anal.sis shows that the frac.al.c.arac.eristic. of far-fiel. diffrac.ion patterns for the 2-D TM struc.ures are determined by the infl.tion rul., whic. have potential.appl.c.tions in the design of optic.l.diffrac.ion devic.s.
