Experimental validation of the diverse incident angle performance of a pulse-width-dependent antenna based on a waveform-selective metasurface in a reverberation chamber
Kaito Ozawa, Hiroki Wakatsuchi
We present experimental validation results of a pulse-width-dependent antenna based on a waveform-selective metasurface that behaves differently according to the incoming waveform,…
Multipath Signal-Selective Metasurface: Passive Time-Varying Interlocking Mechanism to Vary Spatial Impedance for Signals with the Same Frequency
Kaito Tachi, Kota Suzuki, Kairi Takimoto +4
Electromagnetic (EM) multipath interference is difficult to address with passive approaches due to two physical restrictions - the shared frequency of the initial and interfering s…
Experimental and Numerical Validation of Tape-Based Metasurfaces in Guiding High-Frequency Surface Waves for Efficient Power Transfer
K. Suzuki, P. T. Dang, H. Homma +5
We present an effective method for transmitting electromagnetic waves as surface waves with a tape-based metasurface design. This design incorporates silver square patches periodic…
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,…
Metasurface-Inspired Maintenance-Free IoT Tags Characterised in Both Frequency and Time Domains
Masaya Tashiro, Ashif Aminulloh Fathnan, Yuta Sugiura +2
We present metasurface-inspired maintenance-free IoT tags that can be characterised not only by frequency-domain profiles but also by time-domain profiles. In particular, time-doma…
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…
