To Calculate Band Gap in Photonic Crystal in 2D using Finite Difference Time Domain
The band gap for 2D PhC with different modes and different lattice structures using FDTD have been computed. Three PBGs between the first and the second bands, between the second and the third bands and between the fourth and fifth bands are concluded. Simulation results shows that for band structure computation is of 1D PhC using FDTD, it is found that some additional solutions appear, which a...
متن کاملBand Diagram Analysis of Frequency-Dependent Photonic Band-Gap Structures Using FDFD Method
Recently, photonic band-gap (PBG) structures are under intense research due to their various applications in optics, microwave, and antenna engineering. Therefore, the accurate modelling of band diagram of frequency-dependent PBG structures is highly needed because the electric properties of all of the materials depend on frequency. In this paper, a new finite-difference frequency-domain (FDFD)...
متن کاملCompact finite-difference frequency-domain method for the analysis of two-dimensional photonic crystals.
A finite-difference frequency-domain method based on the Yee's cell is utilized to analyze the band diagrams of two-dimensional photonic crystals with square or triangular lattice. The differential operator is replaced by the compact scheme and the index average scheme is introduced to deal with the curved dielectric interfaces in the unit cell. For the triangular lattice, the hexagonal unit ce...
متن کاملElectromagnetic Scattering Using Gpu-based Finite Difference Frequency Domain Method
This paper presents a graphics processing based implementation of the Finite-Difference Frequency-Domain (FDFD) method, which uses a central finite differencing scheme for solving Maxwell’s equations for electromagnetics. The radar cross section for different structures in 2D and 3D has been calculated using the FDFD method. The FDFD code has been implemented for the CPU calculations and the sa...
متن کاملFinite-difference time-domain analysis of band structures in one-dimensional Kerr-nonlinear photonic crystals
We present a new approach for analyzing band structures in one-dimensional Kerr-nonlinear photonic crystals. It combines the finite-difference time-domain method, based on the numerical simulation of oscillating dipole radiation, with the Kerr-nonlinear model. The approach is applied to analyze the band structures in Kerr-nonlinear one-dimensional photonic crystals as a function of the intensit...
