Complementary transmissive ultra-thin meta-deflectors for broadband polarization-independent refractions in the microwave region

引用

Photonics Research 2019年第1期7卷 80-88页

作者： YUEYI YUAN KUANG ZHANG xumin ding BADREDDINE RATNI SHAH NAWAZ BUROKUR QUN WU Department of Microwave Engineering Harbin Institute of Technology State Key Laboratory of Millimeter Waves LEME UPL Université Paris Nanterre

Polarization manipulation is a significant issue for artificial modulation of the electromagnetic(EM) wave, but general mechanisms all suffer the restriction of inherent symmetric properties between opposite ***, a strategy to independently and arbitrarily manipulate the EM wave with orthogonal circular polarizations based on a metasurface is proposed, which effectually breaks through traditional symmetrical characteristics between orthogonal handedness. By synthesizing the propagation phase and geometric phase, the appropriate Jones matrix is calculated to obtain independent wavefront manipulation of EM waves with opposite circular polarizations. Two transmissive ultra-thin meta-deflectors are proposed to demonstrate the asymmetrical refraction of transmitted circularly polarized waves in the microwave region. Simulated transmitted phase front and measured far-field intensity distributions are in excellent agreement, indicating that the transmitted wave with different polarizations can be refracted into arbitrary and independent directions within a wide frequency band(relative bandwidth of 25%). The results presented in this paper provide more freedom for the manipulation of EM waves, and motivate the realizations of various polarization-independent properties for all frequency spectra.

Compact logic operator utilizing a single-layer metasurface

Photonics Research 2022年第2期10卷 316-322页

作者： Zihan Zhao Yue Wang xumin ding Haoyu Li Jiahui Fu Kuang Zhang Shah Nawaz Burokur Qun Wu Advanced Microscopy and Instrumentation Research Center School of Instrumentation Science and EngineeringHarbin Institute of TechnologyHarbin 150080China Department of Microwave Engineering Harbin Institute of TechnologyHarbin 150001China LEME UPLUniv Paris NanterreF92410 Ville d'AvrayFrance

In this paper, we design and demonstrate a compact logic operator based on a single-layer metasurface at microwave frequency. By mapping the nodes in the trained fully connected neural network(FCNN) to the specific unit cells with phase control function of the metasurface, a logic operator with only one hidden layer is physically realized. When the incident wave illuminates specific operating regions of the metasurface, corresponding unit cells are activated and can scatter the incident wave to two designated zones containing logical information in the output layer. The proposed metasurface logic operator is experimentally verified to achieve three basic logic operations(NOT, OR, and AND) under different input signals. Our design shows great application potential in compact optical systems, low-power consumption information transmission, and ultrafast wave-based full signal processing.

在实际应用中有许多场合需要对电磁波的传播进行人工调控,传统的光学器件或者人工电磁介质都是采用三维结构,但传统的三维结构介质很难与其他器件或设备进行集成.利用相位非连续人工电磁表面则可以在传播路径的介质分界面上引入相位突变,进而实现人工调控电磁波.文章在此基础上在微波波段利用构造分界面相位梯度提出了一种异常反射型超表面的设计,用作天线反射面可将圆极化波高效地转化为交叉极化波,为微波段的电磁波人工调控提供了新的手段.根据广义反射定律及斜入射时相位突变修正设计的天线反射面,在X波段可以实现对入射电磁波的人工调控,并通过仿真分析验证了该设计方法的准确性,为人工电磁表面作为天线反射面提供了一种设计思路.
