Latest Patents

Sena Yang holds a patent for "Systems and methods for forming topological lattices of plasmonic merons." This patent describes methods and systems for assembling electron spin and charge to create a topological plasmonic spin texture array. The invention allows for lithography that is not constrained by the diffraction limit of optical systems. The method involves defining the polarization of an optical field of light and a corresponding coupling-structure geometry. It includes providing a coupling structure in a metallic material, which defines a region of the material. By directing light with the defined polarization to the center of this region, a lattice of plasmonic merons is formed, achieving finer contrast resolution than that determined by the Abbe limit.
