August 24, 2020, Our paper (together with Prof. Johannes Courtial), "Transformation cosmology", was published on Physical Review A. In this paper, we propose a way by utilizing transformation optics theory to directly obtain the equivalent isotropic refractive index profiles which are the analogies of some static spaces of general relativity. We find that the analog of de Sitter space is the Poincaré disk, while anti–de Sitter space is equivalent to Maxwell's fish-eye lens. Furthermore, with the isotropic refractivity index profile, we visualize the gravitational lensing effect of black hole from our software Dr TIM.
June 19, 2020, Our paper (together with Assi. Prof. Longfang Ye), "Manipulating Evanescent Waves in a Gradient Waveguide", was published on Phys. Rev. Applied.In this paper, we analyze the manipulation of evanescent waves in a waveguide with gradient-index metamaterials in theory and experiment.

May 4, 2020, Our paper (together with Assi. Prof. Lin Xu, Prof. Hui Liu), "Conformal Landscape of a Two-Dimensional Gradient Refractive-Index Profile for Geometrical Optics" , was published on Phys. Rev. Applied.In this paper, we demonstrate that a flat gradient index optical thin-film waveguide is equivalent to a curved homogenous optical thin film waveguide for light rays by utilizing conformal equivalence.Feb 4, 2020, Our paper, "Bioinspired Conformal Transformation Acoustics", was published on Phys Rev Applied. In this paper, we propose "Bioinspired Conformal Transformation Acoustics": a bioinspired semianalytical conformal acoustics that can predict the evolution of acoustic functions strictly. This is inspired by toothed whales, such as dolphins and porpoises, which can manipulate directional beams by simply deforming their foreheads.
Jan 21, 2020, Our paper (together with Prof. Jian-Hua Jiang), "Plasmon-polaritonic quadrupole topological insulators", was published on Phys Rev B (Rapid Communication).

We fabricated a device with such a topological defect with positive charge in experiments and its related light-bending functionality with laser beams.
