Description
Summary:We report a waveform-selective metasurface that operates at 2.4 GHz band, i.e. one of ISM (Industrial, Scientific and Medical) bands. This structure gives us an additional degree of freedom to control electromagnetic waves and absorbs a particular waveform or pulse width of an incident wave at the same frequency band, while transmitting others. This unique capability is demonstrated using either ideal sinusoidal waves or Wi-Fi signals as a more practical waveform in wireless communications. Especially, this study shows how the waveform-selective metasurface interacts with realistic wireless communication signals from the viewpoint of communication characteristics, such as EVM (Error Vector Magnitude), BER (Bit Error Rate) and phase error. Thus, our study paves the way for extending the concept of waveform selectivity from a fundamental electromagnetic research field to a more realistic wireless communication field to, for instance, mitigate electromagnetic interference occurring at the same frequency band without significantly degrading communication characteristics.
