Cellulose‐Nanofiber‐Based Layered Sub‐Terahertz Absorbing Sheets for B5G/6G Applications
We report a sub‐terahertz absorber made of biodegradable cellulose‐nanofiber (CNF), potentially useful for B5G/6G devices to achieve electromagnetic compatibility in an eco‐friendly way. The absorber is 120 µm thick and consists of two carbon‐nanotube‐dispersed CNF layers and one pure CNF layer.

Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes
We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.

This article presents a hybrid metal‐dielectric metasurface in transmission mode for mid‐infrared (MIR) spectroscopy. Composed of germanium on aluminium cylinders atop a calcium fluoride substrate, the metasurface achieves 80% transmission efficiency at λ = 2.6 µm with a narrow full‐width‐half‐maximum of 0.4 µm.
