✦ Synopsis

Diverse imaging of point source by a two-dimensional
photonic crystal slab with square lattice is studied by the
finite-difference time-domain method. Given proper frequencies,
there seems to be some special directions like channels guiding
the light propagation inside the photonic crystal, along which
some images will be created. Although a frequency employed is
within the range of resulting negative refraction according the
view of [1], the behavior of negative refraction can not been
found. It is suggest that except negative refraction there should
be multiple mechanisms making point image by two dimension
photonic crystal slab.
