A Study on Optimal Design of Polarization-Independent Magneto-Metasurface Isolators Based on Multi-Material Topology Optimization

IEEE Photonics Journal
Metasurface has attracted a lot of attentions because they can realize properties that cannot be achieved with ordinary materials and are easy to be fabricated using established fabrication processes. In this paper, in order to design metasurface without

A compact two-dimensional grating coupler used as a polarization splitter

, 2003
We demonstrate a novel polarization splitter based on a two-dimensional grating etched in a silicon-on-insulator waveguide. The device couples orthogonal modes from a single-mode optical fiber into identical modes of two planar ridge waveguides.

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 ...

Geometric metasurface enabling polarization independent beam splitting [PDF]

, 2018
A polarization independent holographic beam splitter that generates equal-intensity beams based on geometric metasurface is demonstrated. Although conventional geometric metasurfaces have the advantages of working over a broad frequency range and having ...

Polarization independent lattice-coupled terahertz toroidal excitations

, 2023
The toroidal dipole excitation is an important field for metamaterial research because of their low-loss attribute. In this study, we demonstrate numerically and experimentally, a unique polarization independent terahertz metamaterial that modulates a ...

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

Molecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Polarization-Independent All-Optical Regenerator for DPSK Data

Photonics, 2014
We demonstrate polarization-independent simultaneous all-optical phase-preserving amplitude regeneration and wavelength conversion of NRZ differential phase shift keying (DPSK) data by four-wave mixing (FWM) in a semiconductor optical amplifier (SOA ...

Polarization angle independent perfect metamaterial absorber

2014 8th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics, 2014
This paper presents a perfect metamaterial absorber (MA) based on rings and cross wires (RCWs) configuration in microwave frequency regime. Maxima absorption rate is at for simulation and at for experiment, in order. The proposed MA provides perfect absorption with angle of polarization independency.

Liquid biopsy‐based diagnostic evaluation of hypermethylated CpG sites for ovarian cancer diagnosis

Molecular Oncology, EarlyView.
This schematic outlines the workflow from biomarker identification to duplex MethyLight assay validation for epithelial ovarian cancer diagnosis using cfDNA‐based liquid biopsy. Initial screening of hypermethylated CpG candidates (cg02957270, cg10061138 cg00480298, COL2A1) was performed in tissue using ARMS‐PCR, COBRA, qPCR and image analysis. Selected

Polarization-independent longitudinal multi-focusing metalens

Optics Express, 2015
A novel multi-focusing metalens in the longitudinal direction has been proposed and investigated based on the equal optical path principle, which is independent on the incident polarizations and can be suitable for both of the linear and circular polarization incidences simultaneously.
