  • Particles with optical metamaterial shells
    Patent number: 11987737
    Abstract: A metamaterial shell architected on a core particle (comprising organic or inorganic material) so as to form a novel class of structurally hierarchical particle that has degrees of freedom in design parameters stemming from effective optical response of the metamaterial shell and from the electromagnetic modes in the core to elicit optical behaviours that are not easily achievable and designable in particles having simpler or smoother geometries.
    Type: Grant
    Filed: March 1, 2021
    Date of Patent: May 21, 2024
    Assignees: California Institute of Technology, The Regents of the University of Michigan
