Building blocks of photonic integrated circuitry (PIC), optical waveguides, have long been considered transparent. However, the inevitable Fresnel reflection from waveguide facets limits their transparency. This limitation becomes more severe in high

A new design method called the array scattering method for a flat lens made of dielectric cylinders is presented. The method reconstructs the far-field radiation pattern of a 2-D arbitrary geometrical shape dielectric scatterer. Since the method has

A new, composite plasmonic waveguide based electromagnetic cloaking scheme is proposed with Si nano-spacer. Here we show, that the scattering fields of an object located on the cloak do not interact with the evanescent field, resulting in object’s

A new design method for 2D flat lens made of dielectric cylinders called the array scattering method is presented (ASM). The method is unique in that it can design a thin lens with better far field results than conventional homogenization methods. A

Here, we report on an invisibility cloak scheme with composite plasmonic waveguide and metsurface overlayers. Designated structures create a ‘black hole’ which conceal a nano-scale object placed on a waveguide. Using the calculated effective perm

A parametric study on a periodic structure made of thin dielectric cylinders is performed. A Luneburg's lens is chosen for implementation since its medium is non-homogenous. Design rules on the periodic structure's unit cell size are determined and t
