Metamaterials, which are composed of periodic or quasi-periodic sub-wavelength structures (called as meta-atoms), have attracted extensive attention from the fields of optics, electronics, physics, materials and others, due to their extraordinary physical properties [1,2,3]. The advent of metamaterials provides a new concept of designing artificial materials, bringing vigor and vitality to advanced functional materials [4, 5]. Metasurface, as the two-dimensional counterpart of metamaterial, usually refers to planar arrays of meta-atoms arranged in two dimensional (2D) manners [6, 7]. The meta-atoms can modulate nearly all the characteristics of electromagnetic (EM) waves, such as amplitude, phase, polarization and modes, metasurfaces have provided unprecedented degree of freedom (DOF) in manipulating EM waves. A large variety of functional metasurfaces have been presented [8, 9]. In particular, metasurface-based multi-dimensional light manipulation attracts more and more attention due to the increasing demand for more integrated and compact devices [10,11,12]. Typically, integration of multiple functions can be realized by aperture multiplexing in space domain, such as meta-atom combination [13], polarization multiplexing through anisotropic meta-atoms [14] and wavelength multiplexing via dispersion [15] and others. For these metasurfaces, the functions are predefined and cannot be altered. Therefore, they can be called static metasurfaces. Due to the passive nature of static metasurfaces, the integrated multiple functions are limited and are usually contradictory to one another. This necessitates the actively-controlled dynamic metasurfaces, whose functions can be altered or customized according to specific scenarios. Many control manners, such as optical switch, electric biasing, mechanical rotation or displacement, free carrier effect, microfluidic and temperature-induced phase variation, have been applied to dynamic metasurfaces [16,17,18,19,20,21,22,23,24,25,26,27]. With these control manners, time-domain DOF is introduced into metasurfaces, and multifunctional metasurfaces can be greatly enriched via time–space control.

Since the EM responses of meta-atoms can be altered fast and conveniently using voltage biasing, electric control is the most common manners of achieving dynamic metasurfaces, i.e. embedding diodes, varactors and the like within meta-atoms, applying DC voltages to change the effective electrical parameters and thus adjusting responses of meta-atoms upon incident EM waves. On the basis of the electric control manner, the concept of coding metasurface was proposed, in which the responses of meta-atoms can be represented by ‘0’ or ‘1’ [28]. Later, the concept of digital metasurface was further put forward, which bridges the gap between analog responses and digital characterizations of metasurfaces. PIN diodes are commonly used to switch among different functions corresponding to different coding sequences. Moreover, the state of ‘0’ and ‘1’ can also represent high and low levels in digital circuits, which means that the coding sequences can be controlled by Field-Programmable Gate Array (FPGA) [28,29,30,31,32]. Using electronic components and FPGA, programmable metasurfaces (PMs) with multiple or switchable functions can be realized through on-site programming. Further integrated with sensors and driven by pre-defined software, self-adaptive PMs can be realized for a specific scenario [33,34,35]. The self-adaptability significantly improves the response rate by removing human involvement. Nevertheless, for these PMs, switches among different functions generally rely on manual operation when the application scenarios are changed, either by on-site reprogramming or by re-defining the driven software. The fundamental framework is actually wire-connected, manually-controlled and non-real-time switched, which levels down their glamour of intellectualization. Therefore, it is fascinating to construct a fundamental framework that can realize remote, wireless, real-time, mind-controlled functional metasurfaces. Moreover, as the initiator, executor or user of metasurfaces, the involvement and participation of human is usually necessary in many scenarios and it is better for human to directly control the metasurface with their mind. As is well-known, human’s brain will generate brainwaves in the process of thinking. If we can collect brainwaves and use them as the control signals of metasurfaces, we can not only allow the users to control metasurfaces with their mind, but also can improve the response rate of metasurfaces. This will make a big step towards truly intelligent metasurfaces. Figure 1 exhibits the schematic diagram of the mind-controlled metasurfaces, which describes the main flow and design ideas of this work.

In this paper, we propose a framework of realizing remotely mind-controlled metasurface (RMCM) using brainwave extraction module. This framework consists of three parts, i.e. sensor, controller and actuator. The sensor refers to the brainwave module that can record brainwaves and transmit them to the controller via Bluetooth. The controller consists of microprogrammed control unit (MCU) and output terminal. Arduino is selected as the controller in this work. The controller receives brainwave signals from the sensor, converts them into attention signals and then feed the attention signals into the actuator. According to the level of attention intensity, the attention signals fall within four separate intervals which are characterized by four thresholds. The output pins of the controller are connected to the actuator, and the high/low level of output voltage corresponds to the coding 1/0 sequence. The actuator is a PM with PIN diodes embedded within its meta-atoms. Under the switch on/off state of the PIN diodes, a phase difference of 180° will be produced to enable 1-bit coding. The output voltage level sequences from the controller denote different coding sequences on the metasurface, so as to control the scattering pattern. A prototype was fabricated and tested. The test results verify the mind controllability of such a metasurface. Different from the traditional dynamic metasurface, this metasurface could manipulate the EM wave through the real-time response of the human brain, rather than manual operation. Our design maps the thinking of the human brain into metasurface EM modulation, which effectively increases the rate of EM modulation. This work paves a new way to intelligent metasurfaces and may find applications in health monitoring, 5G/6G communications, smart sensors, etc.
