How to do FFT Spectral Analysis

说明：  mat lab designed filter

根据以下的平板光波导在波长为1550 nm时的折射率数据 1.作 出 不 同 波 导 芯 厚 度 d (0<d<15  m)对应的TE模式 与TM模式的色散图； 2.给出满足单模与双模传输的 波导厚度范围。 3.确定包层所需的最小厚度a 与b的值(The refractive index of the optical waveguide data at a wavelength of 1550 nm according to the following plate 1. do not make the same waveguide core thickness d (0 <d <15  m) corresponding to the TE mode And TM mode dispersion map 2. The single-mode and dual-mode transmission is given to meet the Waveguide thickness range. 3. To determine the required minimum thickness of a cladding And the value of b)

一个国外出名的信息隐藏工具H4PGP，好用简单(A well-known abroad, information hiding tools H4PGP, easy to use simple)

matlab code is very good one
