Description: 外国人开发的电磁时域有限差分方法工具包
Electromagnetic Finite-Difference Time-Domain (EmFDTD)
is a basic two-dimensional FDTD code developed at the
School of Electrical Engineering, Sharif University of
Technology.
This code has been written based on the standard
Yee s FDTD algorithm. Applications include propagation,
scattering, and diffraction of electromagnetic waves
in homogeneous and non-homogeneous isotropic media
for in-plane propagating waves. Negative permittivites
or permeabilities as well as dispersion is not included.
Zero, Periodic, and Perfectly Matched Layer boundary
conditions may be selectively applied to the solution
domain.
The program is best suited for study of propagation and
diffraction of electromagnetic waves in Photonic Crystal
structures.
EmFDTD is written in MATLAB language and has been
tested under MATLAB 5.0 and higher versions. Platform: |

Description: This MATLAB M-file implements the finite-difference time-domain solution of Maxwell s curl equations over a two-dimensional Cartesian space lattice comprised of uniform square grid cells.
The computational domain is truncated using the perfectly matched layer (PML) absorbing boundary conditions. The formulation used in this code is based on the original split-field Berenger PML. Exponential time stepping is implemented in the PML regions. The PML regions are labeled as shown in the following diagram: -This MATLAB M-file implements the finite-difference time-domain solution of Maxwell s curl equations over a two-dimensional Cartesian space lattice comprised of uniform square grid cells.

Description: Pablo is a pedagogical low-speed airfoil analysis program written in MATLAB. It uses a one way coupled inviscid + boundary layer model.
The inviscid flow is solved using a Panel Method [1]. Three different kinds of singularity distributions can be used. The boundary layer equations use the inviscid flow velocity provided by the panel method, but the effect of the boundary layer on the inviscid flow is not taken into account, as in Panda [2]. The boundary layer model is described in [3]. It uses Thwaites equations for the laminar part of the flow, and Head s equations for the turbulent part. Michel s criterion is used to locate transition. The drag coefficient is computed using the Squire-Young formula.-Pablo is a pedagogical low-speed airfoil analysis program written in MATLAB.

Description: 在多层共轭自适应光学中,采用相位屏模拟湍流的大气,用以研究湍流大气的最佳分层,确定层边界位置。文中提出了湍流大气的实验室相位屏模拟原理及相位屏个数与边界确定的仿真算法。仿真结果表明。可使用较少的相位屏模拟多层大气湍流,从而使系统结构简化。(In the multi-layer conjugate adaptive optics, the phase screen is used to simulate the turbulent atmosphere, so as to study the optimal stratification of the turbulent atmosphere and determine the boundary position of the layer. In this paper, the principle of phase screen simulation in turbulent atmosphere and the simulation algorithm of the number and boundary of phase screens are proposed. The simulation results show that. A few phase screens can be used to simulate multi-layer atmospheric turbulence, thus simplifying the system structure.) Platform: |
