We describe a multipole method for calculating the modes of microstructured optical fibers.
The method uses a multipole expansion centered on each hole to enforce boundary …

We describe the numerical verifications of a multipole formulation for calculating the
electromagnetic properties of the modes that propagate in microstructured optical fibers. We …

We present a concept of graded photonic crystals used to enhance the control of light
propagation. Gradual modifications of the lattice periodicity make it possible to bend the light …

We present a study of graded photonic crystals presenting a mirage effect. This light bending
is understood through parametric studies of the isofrequency curves. We derive a model …

We present a comprehensive theoretical study of the second harmonic generation (SHG) in
metamaterials consisting of arbitrary distributions of cylindrical nanowires made of …

We report the experimental demonstration of a beam curvature in graded photonic crystals
via a spectacular mirage effect. A two-dimensional structure of metallic rods is constructed to …

We investigate the propagation of electromagnetic waves in two-dimensional doped
photonic crystals. We numerically demonstrate how photonic crystals may be used to …

We investigate the propagation of electromagnetic waves in finite photonic band gap
structures. We analyse the phenomenon of conduction and forbidden bands and we show …

The photonic band gap (PBG) crystals have been used as a perfectly reflecting substrate for
many millimeter wave applications. In his work the fin line directional coupler with PBG …

The model of two-dimensional (2-D) guided-wave photonic band-gap structures based on
the Bloch-Floquet theory is proposed for the first time for both infinite and finite length …
