Optical properties of multilayer optics including negative index materials
Michel Lequime, Boris Gralak, Sebastien Guenneau +2
Negative indices are revisited through the thin-film admittance formalism. Effective indices and phase delay associated with wave propagation through negative index layers are care…
Negative Index Materials: The Key to "White" Multilayer Fabry-Perot
Michel Lequime, Boris Gralak, Sebastien Guenneau +2
The use of negative index materials is highly efficient for tayloring the spectral dispersion properties of a quarter-wavelength Bragg mirror and for obtaining a resonant behavior…
Finite frequency external cloaking with complementary bianisotropic media
Yan Liu, Boris Gralak, Ross. C. McPhedran +1
We investigate the twofold functionality of a cylindrical shell consisting of a negatively refracting heterogeneous bianisotropic (NRHB) medium deduced from geometric transforms. T…
Asymptotic theory of microstructured surfaces: An asymptotic theory for waves guided by diffraction gratings or along microstructured surfaces
Tryfon Antonakakis, Richard V. Craster, Sebastien Guenneau +1
An effective surface equation, that encapsulates the detail of a microstructure, is developed to model microstructured surfaces. The equations deduced accurately reproduce a key fe…
Homogenization Techniques for Periodic Structures
Sebastien Guenneau, Richard Craster, Tryfon Antonakakis +2
In this chapter we describe a selection of mathematical techniques and results that suggest interesting links between the theory of gratings and the theory of homogenization, inclu…
High-frequency homogenization of zero frequency stop band photonic and phononic crystals
Tryfon Antonakakis, Richard Craster, Sebastien Guenneau
We present an accurate methodology for representing the physics of waves, for periodic structures, through effective properties for a replacement bulk medium: This is valid even fo…
