EmFDTD-v1.2r1
说明: 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.(Foreigners developed electromagnetic FDTD method Toolkit Electromagnetic Finite-Difference Time-Domain (EmFDTD) is a basic two-dimensional FDTD code developed at the School of Electrical Engineering, Sharif University of Technology.

数据降维算法
K_L变换是一种最优正交变换,以矢量信号X的协方差矩阵Ф的归一化正交特征矢量q所构成的正交矩阵Q,来对该矢量信号X做正交变换Y=QX,则称此变换为K-L变换(K-LT或KLT)。(Data reduction algorithm K_L optimal orthogonal transform is a transformation to vector signal covariance matrix Ф X normalized orthogonal feature vector composed of q orthogonal matrix Q, to be orthogonal to the vector signal X transformation Y = QX, called the KL transform transform (K-LT or KLT).)

说明: EKF仅仅利用了非线性函数Taylor展开式的一阶偏导部分(忽略高阶项),常常导致在状态的后验分布的估计上产生较大的误差,影响滤波算法的性能,从而影响整个跟踪系统的性能。最近,在自适应滤波领域又出现了新的算法——无味变换Kalman滤波器(Unscented Kalman Filter-UKF)。UKF的思想不同于EKF滤波,它通过设计少量的σ点,由σ点经由非线性函数的传播,计算出随机向量一、二阶统计特性的传播。因此它比EKF滤波能更好地迫近状态方程的非线性特性,从而比EKF滤波具有更高的估计精度。
(EKF only uses non-linear function of the first-order Taylor expansion of some partial derivatives (ignoring higher order terms), often leading to the posterior distribution of the state estimates to generate large errors affect the performance of filtering algorithms, which affect the whole tracking system performance. Recently, the field of adaptive filtering algorithms and the emergence of new- and tasteless transform Kalman filter (Unscented Kalman Filter-UKF). EKF UKF filter is different from the idea that it points through the design of a small amount of σ by σ point spread through the nonlinear function to calculate the random vector first and second order statistical properties of the transmission. Therefore it is better than the EKF filter nonlinear characteristics equation of state approach, which is more than the EKF filter estimation accuracy.)
