Abstract Gesture recognition plays a significant role in human-machine interaction (HMI) system. This paper proposes gesture-controlled reconfigurable metasurface system based on surface electromyography (sEMG) for real-time beam deflection and polarization conversion. By recognizing the sEMG signals of user gestures through pre-trained convolutional neural network (CNN) model, dynamically modulates metasurface, enabling precise control direction state electromagnetic waves.

In this paper, a broadband metamaterial absorber (MA) based on multilayer structure is proposed in the terahertz region. Different from general structure, we designed superimposes with different resonators “horizontal direction” of bottom metal plate. The unit composed several size and dielectric layers which are placed vertically numerical results show that MA has absorption 5 THz to 7.75 THz, rate larger than 80%. A calculation formula first given calculate frequency, compare simulation...
In this work, we present the analysis and design of a perfect metamaterial absorber (MA) based on quarter mode rectangular cavity in terahertz region. This structure is consisted metal plate where three different size cavities are vertically placed on. Based rectangular-cavity-theory, formula proposed to calculate resonant frequency, which provides guidance for designing MAs such type. terms normal incidence, simulated results show that MA has resonance points 4.1301 THz, 4.6051 THz 5.1088...
In this work, we present the analysis and design of a perfect metamaterial absorber (MA) based on circular cavity with one side open in terahertz region. This structure consists metal plate where is vertically placed on. Based circular-cavity-theory, formula can be used to calculate resonant frequency. terms normal incidence, simulated results show that MA has resonance point 6.674 THz, which consistent calculated results. What’s more, distribution E-field, surface current power loss density...
