Abstract: A novel optical fiber grating sensor fabricated using femtosecond laser direct writing technology, integrating 45° and 81° tilted fiber gratings (TFGs), a chirped fiber Bragg grating (CFBG), ...
Abstract: This article proposes a novel method for eliminating the first grating-lobe of wideband multiple-input multiple-output (MIMO) millimeter-wave imaging array. It exploits the position shift ...
