Abstract

Periodic intensity variations as a function of incident and azimuthal angles were observed upon rotating a face-centered-cubic photonic crystal with respect to a linearly polarized microwave beam. These intensity variations also depended on the radiation frequency. We have studied propagating wavelengths that were smaller than, comparable with, and larger than the crystallographic pitches. It is suggested that the observed transmission variations arise from the combination of a periodic structure with transverse confinement of the propagating wave. Such diffraction configurations may permit spatial filtering techniques with subwavelength periodic structures.
