Unequal Wilkinson Power Divider Using Asymmetric Microstrip Parallel Coupled Lines [PDF]
Journal of Intelligent Procedures in Electrical Technology, 2012 An effective method is introduced to overcome the narrow strip width in unequal Wilkinson power divider with high dividing ratio. In the proposed Wilkinson power divider, the separated microstrip lines are replaced by a uniform asymmetrical microstrip ...

Large‐Area Metallic Nanohelices for Engineering Optical Chirality
Small, Volume 22, Issue 13, 3 March 2026.By exploiting the nanoscale engineering of residual stresses in metallic thin films, this method enables scalable fabrication of submicrometer metallic helices with tunable geometry and material versatility. The resulting structures exhibit pronounced chiroptical responses across the mid‐ to near‐infrared range, offering a robust platform for chiral ...
