We develop a point-scattering approach to the plane-wave optical transmission of subwavelength metal hole arrays. We present a real-space description instead of the more conventional reciprocal-space description; this naturally produces interfering resonant features in the transmission spectra and makes explicit the tensorial properties of the transmission matrix. We give transmission spectra simulations for both square and hexagonal arrays; these can be evaluated at arbitrary angles and polarizations.
