Manipulating polarization states of terahertz radiation using metamaterials

New Journal of Physics, 2012
We present a double-ring-chain metamaterial that enables efficient polarization conversion of terahertz waves. The experimental results and numerical simulations reveal that the linear-to-linear polarization rotation and linear-to-elliptic polarization ...

Terahertz polarization conversion with quartz waveplate sets [PDF]

Applied Optics, 2013
We present the results of calculation and experimental testing of an achromatic polarization converter and a composite terahertz waveplate (WP), which are represented by sets of plane-parallel birefringent plates with in-plane birefringence axis. The calculations took into account the effect of interference, which was especially prominent when plates ...

Conversational Polarization: Eight Key Considerations for Communication Scientists

Science Communication
Previous research has largely overlooked how polarization is constituted through conversations. We introduce the concept of “conversational polarization,” highlighting how polarization is socially constructed in conversations about contentious issues. We present eight considerations for communication scientists to study polarization.

Polarization-Tailored Raman Frequency Conversion in Chiral Gas-Filled Hollow Core Photonic Crystal Fibers

, 2019
Broadband-tunable sources of circularly-polarized light are crucial in fields such as laser science, biomedicine and spectroscopy. Conventional sources rely on nonlinear wavelength conversion and polarization control using standard optical components ...

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Ultra-wideband and high-efficiency cross-polarization conversion using a double split ring shaped metasurface for C, X, and Ku-band applications

AIP Advances, 2022
Polarization converters play an important role in practical applications to manipulate the electromagnetic wave. However, the development of a polarization converter that possesses both high conversion efficiency and a wide frequency band is very ...

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

Molecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Metasurface Design Based on S-Shaped Split Ring Resonator for Linear-to-Circular Polarization Conversion

, 2021
In this paper, we proposed a single layered meta-surface linear-to-circular polarization converter based split ring resonator structure. The periodic unit cell of the converter includes nested "S-shaped" and "C-shaped" rings.

Focused polarization hologram with arbitrary polarization to a specified polarization conversion

Optics Express
Polarization devices play a key role in many optical technologies and applications. However, traditional polarization devices are often large and lack integration, and achieving polarization conversion typically requires combining multiple devices, which makes it challenging to realize integrated optical systems.
