Polarization Conversion Mediated Surface Plasmon Polaritons in Extraordinary Optical Transmission through a Nanohole Arrays
… has been reached on the role of incident light polarization. This study presents a simple model that captures Bloch-SPP excitation, including the role of polarization, in general periodic plasmonic structures. Our model predicts that under certain conditions polarization conversion should occur …

Development of conformal reconfigurable metamaterial-based antennas
… meander lines - can be reconfigured into four polarization states. The proposed metasurface becomes a reflector with emptied channels, whereas exhibits linear to cross polarization conversion (or linear to circular polarization conversion) properties when the top (or bottom) layer is filled …

Characterisation of silicon photonics devices
… this work that power do exchange between the two polarization states, therefore the polarization conversion, the power losses and the bending losses will be investigated. It will also shown in here that by applying lateral offsets with coupled waveguides of unequal widths, the insertion loss can …

Energy transfer and localization in molecular crystals
… in molecular crystals result in frequency-conversion and polarization changes. Applied electromagnetic fields of moderate intensity can induce these nonlinear effects without triggering chemical decomposition, offering a mechanism for non-ionizing identification of explosives. We use …

Optimization of silicon photonic devices for polarization diversity applications
… important designs, analysis and optimization of polarization-based devices such as polarization rotator and splitter. Many optical sub-systems integrate with guided wave photonic devices with two-dimensional confinement and high contrast between the core and cladding. The modes present in such …
