Recent activities:

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). In this paper, we propose a lattice of plasmon-polaritonic nanocavities which can realize quadrupole topological insulators by exploiting the geometry-dependent sign reversal of the couplings between the daisylike nanocavities.

Dec 12, 2019, Our paper, "Caustics from Optical Conformal Mappings", was published on Phys Rev Applied. We propose transformation caustics by applying coordinate transformation to the caustic effect. The limit boundaries of caustics can be used to design devices with asymmetric light propagation or light confinement, thus providing an alternative degree of freedom for metamaterials.

Nov 25, 2019, Our paper, "Photonic zero-energy modes in a metal-based Lieb lattice", was published on New Journal of Physics.

Oct 25, 2019: Our paper, "Light rays and waves on geodesic lenses", was published on Photonics Research.

Sep 24, 2019: Our paper, "Conformal optical devices based on geodesic lenses", was published on Opt. Express. We present a special method for conformal transformation optics based on geodesic lenses with special closed surfaces. The requirement is a continuous refractive index profile of dielectrics, which shows the almost perfect performance of designed devices.

Aug 22, 2019: Our paper (together with Prof. Xiancong Lu), "Effect of truncation on photonic corner states in a Kagome lattice", was published on Opt. Lett . We theoretically present a simple nanophotonics platform, where the photonic corner states can be obtained in high frequencies.

Mar 29, 2019: Our paper (together with Profs Hui Liu and Shining Zhu's group), "Conformal singularities and topological defects from inverse transformation optics", was published on Physical Review Applied. In this article, we proposed the "inverse transformation optics", and found that a conformal singularity of a refractive-index profile, with either zero or infinity resulting from a power mapping w=z^a, is equivalent to a topological defect with positive charge or negative charge. We fabricated a device with such a topological defect with positive charge in experiments and its related light-bending functionality with laser beams.

Jan 10, 2019: Our paper, "Illusion elastics in a fluid background", was published on Physical Review Applied. In this article, by using transformation acoustics based on Fabry-P'{e}rot (FP) resonances, we obtain an illusion such that an arbitrary solid object sounds to be like another solid object in a fluid background.

Dec 4, 2018: Our paper, "Universal multimode waveguide crossing based on transformation optics", collaboration work with Prof. Dingshan Gao from Huazhong University of Science and Technology, was published on Optica. In this article, we demonstrate for the first time a universal multimode waveguide star crossing based on transformation optics, which can handle in principle any number of waveguide modes and any number of crossing channels as well.
