Printable Liquid Metal-Textiles for Deformation-Insensitive and Electromagnetically Robust mmWave Devices. [PDF]
Adv Sci (Weinh)We present a textile‐compatible, self‐healing liquid metal ink and a dual‐mask printing technique for high‐resolution patterning. Using this approach, we demonstrate high‐performance millimeter‐wave (mmWave) electronic textiles that exhibit exceptional insensitivity to deformation.

FFT-perustainen spektrianalyysi USRP-ohjelmistoradioalustalla [PDF]
, 2020 Tiivistelmä. Tässä työssä tutustutaan tehotiheysspektrin estimoinnissa käytettyihin menetelmiin ja käytetään USRP-2900 ohjelmistoradiota spektrianalysointiin. Mittauskaistaksi valittiin WLAN-kaista, mutta työssä käytetyllä menetelmällä voi suorittaa mittauksia myös muilla kaistoilla. Työssä käytetyllä menetelmällä mittaus voidaan tehdä kaistalta, jonka

Super-Robust Telecommunications Enabled by Topological Half-Supermodes. [PDF]
Adv Sci (Weinh)Through topological half‐supermode engineering, we realize a valley‐ridge gap waveguide that is directly compatible with conventional waveguides and features topological protection. This design halves the lateral size via a PEC boundary, enabling direct TE₁₀‐mode matching and robust bend‐immune transmission.

Random Time-Space Coding Metasurfaces for Spatial Control of the Temporal Statistics of Electromagnetic Fields. [PDF]
Adv Sci (Weinh)A probabilistic framework based on random time‐space coding metasurfaces enables control of the spatial distribution of electromagnetic fields temporal statistics. By tailoring the marginal and joint distributions of random codes, electromagnetic fields with desired mean and variance patterns are realized, enabling simultaneous transmission and jamming.
