High-frequency homogenization of zero-frequency stop band photonic and phononic crystals [link]Paper  doi  abstract   bibtex   
We present an accurate methodology for representing the physics of waves, in periodic structures,\nthrough effective properties for a replacement bulk medium: this is valid even for media with\nzero-frequency stop bands and where high-frequency phenomena dominate. Since the work of Lord\nRayleigh in 1892, low-frequency (or quasi-static) behaviour has been neatly encapsulated in\neffective anisotropic media; the various parameters come from asymptotic analysis relying upon the\nratio of the array pitch to the wavelength being sufficiently small. However, such classical\nhomogenization theories break down in the high-frequency or stop band regime whereby the wavelength\nto pitch ratio is of order one. Furthermore, arrays of inclusions with Dirichlet data lead to a\nzero-frequency stop band, with the salient consequence that classical homogenization is invalid.\nHigher-frequency phenomena are of significant importance in photonics (transverse magnetic waves\npropagating in infinite conducting parallel fibres), phononics (anti-plane shear waves propagating
