外國人開發的電磁時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.

此工具是arm-linux-GCC交叉編譯工具（cross-3.4.4），這個是我自己編譯的，下載后解壓到/usr/local/arm目錄下，如果你有其它版本的編譯器，你最好在編譯其它文件時指定這個目錄，我試過，我用它編譯了u-boot1.2.0沒有問題，這個交叉編譯器編了好長時間，我之前在網上搜了好長時間，但是沒搜到，所以今天貢獻出來，免得大家還得費時間去編譯，我現在用是沒有問題，如果有問題請多指教。希望熱愛linux的同志們多貢獻點好東西出來！

傳統的以太網是一個廣播型網絡，網絡中的所有主機通過HUB 或交換機相連，處在 同一個廣播域中。HUB 是物理層設備，沒有交換功能，接收的報文會向所有端口轉 發；交換機是鏈路層設備，具備根據報文的目的MAC 地址進行轉發的能力，但在 收到廣播報文或未知單播報文（報文的目的MAC 地址不在交換機MAC 地址表中） 時，也會向除交換機報文入端口之外的所有端口轉發。 上述情況使網絡中的主機會收到大量并非以自身為目的地的報文，在浪費大量帶寬 資源的同時，也造成了嚴重的安全隱患。 隔離廣播域的傳統方法是使用路由器，但是路由器成本較高，而且端口較少，無法 劃分細致的網絡。 為解決以太網交換機在LAN 中無法限制廣播的問題，出現了VLAN（Virtual Local Area Network，虛擬局域網）技術。

If you are using Internet Explorer on Windows XP Service Pack 2, there is a security restriction disallowing scripts to run in files opened on your local machine. When you first try to run the examples, you will most likely get a message saying, "To help protect your security, Internet Explorer has restricted this file from showing active content that could access your computer." To see the example, you must click on the message and select "Allow Blocked Content". JavaScript高級程序設計 里面自代源碼

程序是根據vidcat改的,只能抓PPM的圖. makefile的內容如下,請注意打小寫: cc=gcc #cflags=-i/firendly-arm/kernel/include -i/usr/local/arm/2.95.3/arm-linux/include -wall -dhave_libjpeg #-dvideo_dev=\"/dev/v4l/video0\" -dversion=\"0.7.2\" cflags=-wall -dvideo_dev=\"/dev/video0\" -dversion=\"0.7.2\" camsnap: camsnap.c 用法如下: camsnap -v -s 420x420 -o my.ppm 這兒請注意:s 的大小必需是8能整除的倍數. 這個程序我是在rh9下作的,需要交叉編譯的朋友就把注釋去掉,再給下面的注釋就可以了.
