Perfect Nonreciprocal Absorption Based on Metamaterial Slab
In order to achieve nonreciprocal absorption, we design a metamaterial slab made of arrays of tilted metal layers. Through studying the extraordinary material dispersion, we derive the transfer matrix to calcu...

Dispersionless and slow unidirectional air waveguide
Unidirectional waveguides and slow light waveguides both play the key roles in the modern communication system. The unidirectional waveguides do not support slow light. The traditional slow light waveguides ar...

Tunable Nonreciprocal Tunneling Based on Nonsymmetric Magnetoplasmonic Resonance Structure
In order to achieve nonreciprocal transmission, we design an optical system composed of a sandwiched structure (magneto-optical media/metal/magneto-optical media) and a pair of coupling prisms. Using the devel...

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...

Achieving Transparent Photonic Band in Regular One-Dimensional Photonic Crystal
A transparent photonic band can be found in a regular one-dimensional photonic crystal structure through proper conditions. Unlike a conventional pass band with a rapid oscillation within it, the transparent p...

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...

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...
