| Outline of Final Research Achievements |
We have studied the possibility of using pinhole/slit array as a waveguide. In this structure, opaque pinholes/slits are aligned on a straight line with equal spacing. It is shown that the loss per unit length is proportional to square root of the spacing of the pinholes/slits. Though this dependence is not quite efficient in practice, such structure can be used to guide light of special wavelength or matter wave for which transparent material or material with high reflectivity is not available.
