Abstract BaFe12− xNbxO19 (BFNO, x= 0‐0.6) powders with Nb5+ substituting for Fe3+ were
prepared by sol‐gel method. The formation process and electromagnetic (EM) wave …

For the sol–gel-derived BaFe12− xNbxO19 (x= 0–0.6), coercivity (Hc) and saturation
magnetization (Ms) vary from 3.53–0.85 kOe and 70.3–53.8 emu g− 1 to 1.02–0.22 kOe and …

We propose and demonstrate a novel design of a multi-arm bowtie antenna (MABA) able to
provide wideband field enhancement (FE). The FE is a looked-for parameter of antennas in …
