Cellulose‐Nanofiber‐Based Layered Sub‐Terahertz Absorbing Sheets for B5G/6G Applications

Advanced Materials Technologies, EarlyView.
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.

Reconfigurable Microwave Filter for Simultaneous Wireless Information and Power Transfer [PDF]

2025 IEEE Wireless Power Technology Conference and Expo (WPTCE)
This work presents a novel design approach for a reconfigurable filter with two resonance points, enabling a wider tuning range and improving spectrum utilization for simultaneous wireless information and power transfer (SWIPT) transmitters. A T-shaped structure is used to control two resonant points to control the change in the passband of the filter.
