N2 - Spatially dispersive (also known as non‐local) electromagnetic media areconsidered where the parameters defining the permittivity relation vary periodically.Maxwell's equations give rise to a difference equation corresponding to the Floquet modes.A complete set of approximate solutions is calculated which are valid when theinhomogeneity is small. This is applied to inhomogeneous wire media. A new feature arises when considering spatially dispersive media, that is the existence of coupled modes.
