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…

Inkjet printed intelligent reflecting surface (IRS) for indoor applications
Kairi Takimoto, Kazutomo Nakamura, Peter Njogu +7
A passive, low-cost, paper-based intelligent reflecting surface (IRS) is designed to reflect a signal in a desired direction to overcome non-line-of-sight scenarios in indoor envir…
