In this paper, the transmission characteristic in nano-size metallic photonic crystals (MPCs) is studied with the finite
difference time domain (FDTD) method. It's show that the size and the layout of the metal decide the transfer
characteristic of the metallic photonic crystals.
Using plane wave expansion (PWE) method and finite-difference time-domain (FDTD) method, we study the photonic band gap (PBG) and transmission properties of two-dimensional photonic crystals (PCs). A holographic fabrication design is used to construct the two-dimensional PCs in our work. To produce the lattice holographically, we use an equation to demonstrate a light intensity distribution. In this equation, there are several variant to control the lattice constant, the shape of dielectric columns, etc. The PBG calculation results using PWE method and FDTD method agree with each other very well.
