Plasmonic nanohelix arrays are shown to interact with electromagnetic fields in ways not typically seen ordinary matter. Chiral metamaterials (CMMs) feature sizes small respect the wavelength of visible light a promising route experimentally achieve such phenomena as negative refraction without need for simultaneously ε and μ. Here we only show that giant circular dichroism is achievable hexagonally arranged plasmonic arrays, but can precisely tune optical activity via morphology lattice...
Complex, hybrid nanohelices fabricated by dynamic shadow growth in a high-throughput manner exhibit novel optical, magnetic and mechanical properties.
We report on the enhanced optical properties of chiral magnetic nanohelices with critical dimensions comparable to ferromagnetic domain size. They are shown be at room temperature, have defined chirality, and exhibit large activity in visible as verified by electron microscopy, superconducting quantum interference device (SQUID) magnetometry, natural circular dichroism (NCD), (MCD) measurements. The structures magneto-chiral (MChD), which directly demonstrates coupling between their...
Nanoplasmonic systems are valued for their strong optical response and small size. Most plasmonic sensors to date have been rigid passive. However, rendering these structures dynamic opens new possibilities applications. Here we demonstrate that nanoparticles can be used as mechanical selectively probe the rheological properties of a fluid in situ at nanoscale microscopic volumes. We fabricate chiral magneto-plasmonic nanocolloids actuated by an external magnetic field, which turn allows...
To exploit the full potential of transverse spatial structure light using Laguerre-Gaussian basis, it is necessary to control azimuthal and radial components photons. Vortex phase elements are commonly used generate these modes light, offering precise over index but neglecting radially dependent amplitude term, which defines their associated corresponding profile. Here, we experimentally demonstrate generation high-purity beams with a single-step on-axis transformation implemented dielectric...
We describe a novel polarization interferometer which permits the determination of refractive indices for circularly-polarized light. It is based on Jamin-Lebedeff interferometer, modified with waveplates, and us to experimentally determine nL nR respectively left- right-circularly polarized modes in cholesteric liquid crystal. Whereas optical rotation measurements only circular birefringence, i.e. difference (nL - nR), also their absolute values. report crystal region selective (Bragg)...

We describe how physical vapor deposition coupled with micelle-nanolithography-seeded substrates permits the growth of metamaterials 3D structural and material control at nanoscale. Novel plasmonic hybrid structures tuned optical response from UV to near IR are demonstrated.
Purpose: The aim of this study was to compare the effect eight weeks physical and mental rotation training on balance falling elderly women. Method: present is a quasi-experimental with pre-test, post-test two-way ANOVA, which also t-test designed. Tools included: questionnaire functional reach test. participants 36 patients (12 subjects in three groups training, control group) have been randomly selected among women an Centre Tabriz. program administered two for weeks, at sessions week...
