Multi-band spin-selective transmission and reflection in bi-layer T-shaped metamaterial

open access: yesResults in Physics, 2023
The control of the spin angular momentum of light plays an irreplaceable role in modern photon applications. In this work, we proposed a chiral metamaterial based on a bi-layer T-shaped structure.

Channel Polarization: A Method for Constructing Capacity-Achieving Codes for Symmetric Binary-Input Memoryless Channels [PDF]

open access: yesIEEE Transactions on Information Theory, 2008
A method is proposed, called channel polarization, to construct code sequences that achieve the symmetric capacity I(W) of any given binary-input discrete memoryless channel (B-DMC) W.

Two-Dimensional Quasi-Periodic Diffraction Properties of the Scalar and Vector Optical Fields

open access: yesPhotonics, 2023
As is known, quasi-periodicity attracts great attention in many scientific regions. For instance, the discovery of the quasicrystal was rewarded the Nobel Prize in 2011, leading to a series of its applications.

Phase encoded quantum key distribution up to 380 km in standard telecom grade fiber enabled by baseline error optimization

open access: yesScientific Reports, 2023
Phase encoding in quantum key distribution (QKD) enables long-distance information-theoretic secure communication in optical fibers. We present a novel theoretical model characterizing errors from various sources in practical phase encoding-based QKD ...

Manipulating Transverse Spin Angular Momentum with Symmetrically Modulated Hybridly Polarized Vector Optical Field

open access: yesPhotonics, 2022
Transverse spin angular momentum (SAM) of photon, also known as ‘photonic wheel’, has attracted much attention, owing to its extraordinary properties and broad application prospect. Thus, it is essential to flexibly manipulate the transverse SAM in order

Non-Markovian speedup evolution of a center massive particle in two-dimensional environmental model

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
A two-dimensional ray model is introduced to realize the non-Markovian speedup evolution of a center massive particle gravitationally coupled to a controllable environment (multilayer arrangement of the massive particles). By controlling the environment,

Simulated Studies of Polarization-Selectivity Multi-Band Perfect Absorber Based on Elliptical Metamaterial with Filtering and Sensing Effect

open access: yesPhotonics, 2023
In this work, the Ag-SiO2-Ag metamaterial with elliptical nano-slits was proposed to investigate the multi-band polarization-dependent perfect absorber.

Macrophage Polarization States in the Tumor Microenvironment

open access: yesInternational Journal of Molecular Sciences, 2021
The M1/M2 macrophage paradigm plays a key role in tumor progression. M1 macrophages are historically regarded as anti-tumor, while M2-polarized macrophages, commonly deemed tumor-associated macrophages (TAMs), are contributors to many pro-tumorigenic ...

Unsupervised learning of pixel clustering in Mueller matrix images for mapping microstructural features in pathological tissues

open access: yesCommunications Engineering, 2023
In histopathology, doctors identify diseases by characterizing abnormal cells and their spatial organization within tissues. Polarization microscopy and supervised learning have been proved as an effective tool for extracting polarization parameters to ...

Control of quantum dynamics: non-Markovianity and speedup of a massive particle evolution due to gravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We illustrate two linear configurations (one-side model and two-side model) for implementing a non-Markovian speedup evolution of a massive particle gravitationally coupled with a controllable environment: multiple massive particles.
