Broadband and Tunable Microwave Absorption Properties from Large Magnetic Loss in Ni–Zn Ferrite Open
Highly effective electromagnetic (EM) wave absorber materials with strong reflection loss (RL) and a wide absorption bandwidth (EBW) in gigahertz (GHz) frequencies are crucial for advanced wireless applications and portable electronics. Tr…

Relaxation dynamics of water in the vicinity of cellulose nanocrystals Open
Water molecules near cellulose nanocrystals (CNCs; produced via sulfuric acid-catalyzed hydrolysis) are believed to relax slower than those in the bulk liquid, which may result in unique properties of CNC aqueous dispersions. This study an…

A novel, all-dielectric, microwave plasma generator towards development of plasma metamaterials Open
A proof of concept for a microwave microplasma generator that consists of a halved dielectric resonator is presented. The generator functions via leaking electric fields of the resonant modes — TE 01δ and HEM 12δ modes are explored. Comput…
