Frequency-Hopping Wave Engineering with Metasurfaces
Hiroki Takeshita, Ashif Aminulloh Fathnan, Daisuke Nita +2
Wave phenomena can be artificially engineered by scattering from metasurfaces, which aids in the design of radio-frequency and optical devices for wireless communication, sensing,…
Unsynchronized Reconfigurable Intelligent Surfaces with Pulse-Width-Based Design
Ashif Aminulloh Fathnan, Kairi Takimoto, Mizuki Tanikawa +3
In this correspondence, we present a reconfigurable intelligent surface (RIS) that reflects an incident signal to the desired direction, depending on the pulse width. This unique r…
Method for Extracting the Equivalent Admittance from Time-Varying Metasurfaces and Its Application to Self-Tuned Spatiotemporal Wave Manipulation
Ashif Aminulloh Fathnan, Haruki Homma, Shinya Sugiura +1
With their self-tuned time-varying responses, waveform-selective metasurfaces embedded with nonlinear electronics have shown fascinating applications, including distinguishing diff…
