Query: Theory of Optical Transmission through Elliptical Nanohole Arrays   We present a theory which explains (in the quasistatic limit) the
experimentally observed [R. Gordon, {\it et al}, Phys. Rev. Lett. {\bf 92},
037401 (2004)] squared dependence of the depolarization ratio on the aspect
ratio of the holes, as well as other features of extraordinary light
transition. We calculated the effective dielectric tensor of a metal film
penetrated by elliptical cylindrical holes and found the extraordinarily light
transmission at special frequencies related to the surface plasmon resonances
of the composite film. We also propose to use the magnetic field for getting a
strong polarization effect, which depends on the ratio of the cyclotron to
plasmon frequencies.
