Ultra-wideband Antireflection Assisted by Continuously Varying Temporal Medium
Yi Zhang, Liang Peng, Zhengjie Huang +2
We demonstrate that reflectionless propagation of electromagnetic waves between two different materials can be achieved by designing an intermediate temporal medium, which can work…
Quasi-BIC laser enabled by high-contrast grating resonator for gas detection
H. Zhang, T. Wang, J. Tian +9
In this work, we propose and numerically investigate a two-dimensional microlaser based on the concept of bound states in the continuum (BIC). The device consists of a thin gain la…
Transverse photon spin beyond interfaces
Liang Peng, Lingfu Duan, Kewen Wang +6
Photons possess spin degree of freedom, corresponding to clockwise and counter clockwise rotating direction of the fields. Photon spin plays an important role in various applicatio…
Giant Asymmetric Radiation from an Ultrathin Bianisotropic Metamaterial
Liang Peng, Kewen Wang, Yihao Yang +4
Unidirectional radiation is of particular interest in high-power lasing and optics. Commonly, however, it is difficult to achieve a unidirectional profile in such a system without…
The scattering of a cylindrical invisibility cloak: reduced parameters and optimization
Liang Peng, Lixin Ran, N. Asger Mortensen
We investigate the scattering of 2D cylindrical invisibility cloaks with simplified constitutive parameters with the assistance of scattering coefficients. We show that the scatter…
Achieving Anisotropy in Metamaterials made of Dielectric Cylindrical Rods
Liang Peng, Lixin Ran, Niels Asger Mortensen
We show that anisotropic negative effective dispersion relation can be achieved in pure dielectric rod-type metamaterials by turning from the symmetry of a square lattice to that o…
