Angular dependence of electric and magnetic mirrors of a single-layer terahertz metasurface

, 2021
We experimentally observed electromagnetic mirror in a single-layer THz metasurface and studied the effect of incident angle on the performance. The magnetic and electric mirror performance is still maintained for incident angle up to 10º.

Simplified radar architecture based on information metasurface

Nature Communications
Modern radar typically employs a chain radio-frequency (RF)-digital architecture, imposing high costs, substantial hardware burdens, and integration challenges. Here, we propose a simplified radar architecture based on space-time-coding (STC) information

Extracellular matrix remodeling and immune reprogramming drive residual tumor progression of liver cancer after incomplete microwave ablation

Molecular Oncology, EarlyView.
Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

Second-order bandpass frequency selective surface for terahertz applications

, 2014
In this paper, a two-layered frequency selective surface with miniaturized elements is proposed for millimeter wave and terahertz applications. The advantages of this design are a harmonic free transmission response and low sensitivity of its frequency ...

A Multi-Layer Spoof Surface Plasmon Polariton Waveguide With Corrugated Ground

IEEE Access, 2017
Due to the unique properties of field confinement and enhancement, spoof surface plasmon polaritons (SPPs) are considered as special modes to break many challenges in traditional electronic and microwave engineering.

Effect of terahertz irradiation on DNA damage repair in living cells

FEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

Millimeter Wave Substrate Integrated Waveguide Antennas: Design and Fabrication Analysis [PDF]

, 2009
The paper presents a new concept in antenna design, whereby a photo-imageable thick-film process is used to integrate a waveguide antenna within a multilayer structure. This has yielded a very compact, high performance antenna working at high millimeter-

High-Order Modes Analysis of Complex Plasmonic Surface Using the Field-Network Joint Solution

IEEE Access, 2019
The plasmonic surface is made of metallic surface with deep sub-wavelength decorations, which are designed to mimic the surface plasmon polaritons at lower frequency. Recently, high-order modes in some special structures are analyzed. In order to analyze
