| Outline of Final Research Achievements |
This study developed artificially engineered periodic structures, the so-called metasurfaces, together with circuit elements including schottky diodes, which led to creating a new kind of electromagnetic characteristics, namely, waveform selectivity. As a previous study we had reported metasurfaces that absorb short pulses, which are in general typical waveforms of electromagnetic noise, while transmitting long pulses or continuous waves even at the same frequency. In contrast, this study developed metasurfaces that absorb long pulses more effectively than short pulses. Additionally, we realised other types of waveform selectivities that allowed us to absorb or transmit arbitrary pulses in between, while both of short and long pulses were respectively transmitted and absorbed. As a consequence, these new characteristics are expected to give us an additional degree of freedom to control electromagnetic waves and sense different waves even at the same frequency.
