The authors present metasurface-inspired maintenance-free IoT tags that can be characterized by both frequency-domain and time-domain profiles. The waveform-selective mechanisms of circuit-based metasurfaces allow the tags to behave differently at the same frequency based on the pulse duration of the incident wave. The proposed designs are validated numerically and experimentally, and potentially contribute to increasing the capacity of IoT tags within a single wireless network while reducing maintenance effort.
The authors present metasurface-inspired maintenance-free Internet of things (IoT) tags that can be characterised not only by frequency-domain profiles but also by time-domain profiles. In particular, time-domain characterisation is made possible by implementing the waveform-selective mechanisms of recently developed circuit-based metasurfaces that behave differently, even at the same frequency, in accordance with the pulse duration of the incident wave. The proposed designs are numerically and experimentally validated and potentially contribute to accommodating an increasing number of IoT tags within a single wireless network while reducing maintenance effort.
