IIR数字滤波器课程设计~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(IIR digital filter design courses ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~)

本程序已被本人整理到WORD文档中，编程语言为MATLAB，程序中首先利用非递归法产生滤波器系数，生成相关高斯杂波，直接对杂波信号作FFT变换，结果取模平方后除以长度N,即可得到杂波的功率谱，设计参数皆在文档中表明。此程序已经验证是正确可执行的，并能生成图形，值得下载！( This program has been organized into WORD document I, the programming language MATLAB, the program produced the first method using non-recursive filter coefficients to generate the relevant Gaussian clutter, clutter signals directly to FFT transform, the result after the square modulus divided by the length of the N, can be obtained the power spectrum of clutter, design parameters are indicated in the document. This procedure has been verified is correct executable, and can generate the graph, it is worth to download!)

A new method for periodic scattering problems using 2nd kind boundary integral equations and the free-space Green s function, adding extra degrees of freedom on the unit cell walls, and imposing quasi-periodicity in an expanded linear system.(A new method for periodic scattering problems using 2nd kind boundary integral equations and the free-space Green s function, adding extra degrees of freedom on the unit cell walls, and imposing quasi-periodicity in an expanded linear system. This avoids the problems with the standard approach, namely: the quasi-periodic Green s function is slow to evaluate, it diverges at Wood s anomalies, and it does not handle large aspect ratios well. Our new approach cures all three issues, and can easily be `wrapped around an existing code (e.g. fast-multipole acceleration) for the isolated-obstacle scattering problem. It includes the latest talk slides: "A new integral representation for quasi-periodic scattering problems in two dimensions")
