Fabrication and applications of pillar bowtie nanoantenna arrays
… technique and applications of a pillar bowtie nanoantenna (p-BNA). We use different tools to fabricate our nanostructure, namely, electron lithographic tools, evaporator and plasma chambers. The theory of operation of the machines, especially electron beam lithography for higher …

Pillar-supported plasmonic nanoantennas for optical nanotweezers and optical audio applications
… within the nanometer-sized gaps of plasmonic bowtie nanoantennas (BNAs) are orders of magnitude larger than those of conventional optical tweezers. Accordingly, plasmon-enhanced gradient forces can both significantly relax constraints for microparticle manipulation and offer a route for …

Flat optics based on patterned nanostructures for concentrating light
… both nanostructured plasmonic or metal nanoantennas with deeply subwavelength features, and dielectric nanostructured surfaces that are fabricated by two-photon lithography. In the former case, we developed pillar-supported Au bowtie nanoantennas (pBNAs), and found that light …
