ATTENUATION IN EXTENDED STRUCTURES COATED WITH THIN MAGNETO-DIELECTRIC ABSORBER LAYER

Reconstruction of a Perfectly Conducting Obstacle Coated with a Thin Dielectric Layer

We consider the inverse scattering problem consisting in the identification of a perfectly conducting obstacle coated with a thin layer of a dielectric material from few far field measurements at a fixed frequency. We propose in this talk an iterative procedure to retrieve the scatterer and the coating. Solving the forward problem is computationally expensive in this case and we shall use an ap...

Improving the optical properties of thin film plasmonic solar cells of InP absorber layer using nanowires

In this paper, a thin-film InP-based solar cell designed and simulated. The proposed InP solar cell has a periodic array of plasmonic back-reflector, which consists of a silver layer and two silver nanowires. The indium tin oxide (ITO) layer also utilized as an anti-reflection coating (ARC) layer on top. The design creates a light-trapping structure by using a plasmonic back-reflector and an an...

Cyclotron frequency coupled enhancement of Kerr rotation in low refractive index-dielectric/magneto-optic bilayer thin-film structures

Temperature Tunability of Dielectric/ Liquid Crystal / Dielectric Photonic Crystal Structures

Recently, photonic crystals doped with liquid crystal (LC) material havegained much research interest. In this article new ternary one-dimensional photoniccrystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwichedby two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2,SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53. The effect ofte...

Magneto-plasmonics in graphene-dielectric sandwich.

In this paper, dispersion properties and field distributions of surface magneto plasmons (SMPs) in double-layer graphene structures at room temperature are studied. It is found that, the dispersion curves of both symmetric and antisymmetric SMPs modes split into several branches/bands when a magnetic field is applied perpendicularly to the graphene surface. Surprisingly, the lowest energy SMP b...
