    Exception point induced flat-band and waveguide laser

    In order to study the exceptional point (EP) properties in the photonic crystal waveguide, we construct the two-dimensional photonic crystal waveguide with the parity–time symmetry configuration. With the calc...

    Transmission mode of one-dimensional phononic crystal based on coupling of total evanescent waves

    In order to obtain the transmission properties of one-dimensional phononic crystal under total evanescent waves, we design structure model. Basing on the basic acoustic wave equations and boundary condition as...

    Tailoring radiation pattern through designed structures using near-zero-index materials

    Due to the zero phase variation and impedance matching to free space, zero-index material is found to have applications in tailoring the electromagnetic radiation patterns. We design a two-dimensional rectangu...

    Ultra-compact resonator with orthogonally polarized dual-wavelength output based on layered epsilon-negative and anisotropic materials

    We propose a resonator based on a sandwich structure composed of the epsilon-negative and anisotropic materials. In view of the numerical method, we study its transmission properties. This ultra-compact struct...

    Polarization-independent narrow bandpass filter and narrow transmission-angle filter based on photonic heterostructures composed of single-negative materials

    We propose a photonic heterostructure consisting of two substructures composed of single-negative materials. Calculating the transmission spectra, we find that only the electromagnetic wave within a narrow ban...

    Goos-Hänchen shift from an anisotropic metamaterial slab

    We have theoretically and numerically investigated the Goos-Hänchen shift (the lateral shift) from the anisotropic metamaterial slab. The sign and degree of the shift can be determined by the choices of the el...

    Study of superluminal-pulse propagation in one-dimensional photonic crystals by the FDTD method

    We study the pulse propagation in a one-dimensional photonic crystal using the finite-difference time-domain method. The wave propagation inside the crystal is the result of superposition of forward and backwa...

    Light pulse propagation in one-dimensional photonic crystal: An FDTD analysis

    Light-pulse propagation in one-dimensional photonic crystals is studied by a finite-difference time-domain method. The effect of the group-velocity dispersion is connected with the center frequency of the ligh...

    Standing wave localized within one-dimensional photonic crystal with defect

    When a photonic crystal with defect is illuminated with a light pulse, a standing wave of light can be excited when the frequency of the defect mode is within the pulse spectrum and the temporal width of the l...
