Gradient refractive index (GRIN) materials are of interest for various applications where
transformation optic principles can be applied to the design of improved photonic and …

Spatially-variant photonic crystals (SVPCs), in which the orientation of the unit cell changes
as a function of position, are shown to be capable of abruptly controlling light beams using …

Spatial transforms are a popular technique for designing periodic structures that are
macroscopically inhomogeneous. The structures are often required to be anisotropic …

An efficient backbone is introduced for optical integrated circuits at Mid-IR region using PbTe
(n PbTe∼ 6) as the background material in a hole-type 2D square lattice photonic crystal in …

Photonic crystals can be engineered so that the flow of optical power and the phase of the
field are independently controlled. The concept is demonstrated by creating a self …

This chapter introduces the tools and methodologies that can be used to engineer the
dispersion and anisotropy of periodic electromagnetic structures. The theory and concepts …

Concealing objects by making them invisible to an external electromagnetic probe is coined
by the term “cloaking.” Cloaking devices, having numerous potential applications, are still …

We propose a simple, fast, and accurate method to design complex layered photonic crystal
structures that exhibit mesoscopic self-collimation. We apply this method to the control of the …

In summary, the utilization of Legendre polynomial expansion in the modal analysis of
stratified dielectric layers with doubly periodic permittivity profiles offers a departure from …
