  We present a highly purposive technique to optically induce periodic photonic
lattices enriched with a negative defect site by using a properly designed
nondiffracting beam. As the interference of two or more nondiffracting beams
with adequate mutual spatial frequency relations in turn reproduces a
nondiffracting beam, we adeptly superpose a hexagonal and a Bessel beam to
create the nondiffracting defect beam of demand. The presented
wavelength-independent technique is of utmost universality in terms of
structural scalability and does not make any specific requirements to the
photosensitive medium. In addition, the technique is easily transferable to all
pattern-forming holographic methods in general and its application is highly
appropriate e.g. in the fields of particle as well as atom trapping.
