Multi-Band Waveform-Selective Metasurfaces Transmitting Continuous Waveforms Based on More Than One Frequency

摘要

This study presents metasurfaces designed to selectively transmit electromagnetic waves even at the same frequency depending on their waveforms or pulse widths. In particular, we demonstrate such waveform-selective metasurfaces operating not only at a single frequency band but also at several bands, which leads to providing an additional selectivity of scattering control by frequency combination, compared to conventional metamaterials responding to a single frequency component. Hence, multi-band waveform-selective metasurfaces are expected to give us a new degree of freedom to address existing electromagnetic issues and challenges.
