This research introduces metasurfaces capable of scattering waves based on two variables: frequency and pulse width. These metasurfaces use transient circuits to create variable scattering profiles in response to different frequency sequences, breaking the conventional linear frequency concept. This passive, self-tunable approach, akin to frequency hopping in wireless communication, advances wave engineering by overcoming the limitations of classical systems.
