Abstract: By using gateway systems on large 32-bit platforms, networks of small, 8- and 16-bit microcontrollers can be monitored and controlled over the Internet. With embedded Linux, these gateways are easily moved from full-blown host PCs to embedded platforms like the PC104. In this class you will learn about hardware platforms that support embedded Linux, Linux kernel configuration, feature selection, installation, booting and tuning.

光子晶体的能带图计算，其实质就是电磁本征值（复矢量场）的问题。利用平面波展开磁场，引入f(r)=1/eps(r)，再利用倒格矢G将f(r)展开，将两者代入光子晶体的支配方程，最后得到一个平面波展开的方法的线性方程组，最终转化为求解其特征值向量的问题。(Energy band diagram of the photonic crystal, its essence is the electromagnetic eigenvalues ​ ​ (complex vector field).The linear plane wave expansion magnetic field, the introduction of f (r) = 1/eps (r), re-use reciprocal lattice vector G will expand f (r), the two substituted into the governing equations of the photonic crystal, and finally get a plane wave expansionequations, and ultimately into solving the problem of its eigenvalues​ ​ .)
