Concentric Circular Grating Generated by the Patterning Trapping of Nanoparticles in an Optofluidic Chip
Due to the field enhancement effect of the hollow-core metal-cladded optical waveguide chip, massive nanoparticles in a solvent are effectively trapped via exciting ultrahigh order modes. A concentric ring structure of the trapped nanoparticles is obtained since the excited modes are omnidirectional...
