Metasurfaces for Efficient Digital Noise Absorption
Ryoya Aihara, Hiroki Wakatsuchi
We numerically demonstrate two types of metasurface absorbers to efficiently absorb digital signals. First, we show that the digital waveforms used in this study contain not only a…
Metasurface Sensing Difference in Waveforms at the Same Frequency with Reduced Power Level
Mizuki Tanikawa, Daiju Ushikoshi, Kosei Asano +4
We numerically demonstrate a new type of waveform-selective metasurface that senses the difference in incoming waveforms or pulse widths at the same frequency. Importantly, the pro…
Experimental demonstration of waveform-selective metasurface varying wireless communication characteristics at the same frequency band of 2.4 GHz
D. Ushikoshi, M. Tanikawa, K. Asano +4
We report a waveform-selective metasurface that operates at 2.4 GHz band, i.e. one of ISM (Industrial, Scientific and Medical) bands. This structure gives us an additional degree o…
Waveform-selective metasurfaces with normal waves at the same frequency
Hiroki Wakatsuchi
Waveform-selective metasurfaces, reported by Wakatsuchi et al. in 2014, have enabled us to distinguish different surface waves even at the same frequency in accordance with their w…
Waveform-dependent absorbing metasurfaces
Hiroki Wakatsuchi, Sanghoon Kim, Jeremiah J. Rushton +1
We present the first use of a waveform-dependent absorbing metasurface for high-power pulsed surface currents. The new type of nonlinear metasurface, composed of circuit elements i…
Waveform Selectivity at the Same Frequency
Hiroki Wakatsuchi, Daisuke Anzai, Jeremiah J. Rushton +3
Electromagnetic properties depend on the composition of materials, i.e. either angstrom scales of molecules or, for metamaterials, subwavelength periodic structures. Each material…
