一种多目标优化算法的matlab程序，能够实现大量目标的同时优化，对多目标优化算法的学习很有帮助(a multi-object optimization matlab program,can optimize large object at meantime it will contribute to those who want to study muti-object optimization algorithm)

2D-potential problemas using Boundary Element Method

Skin effect is the tendency of an alternating electric current (AC) to distribute itself within a conductor with the current density being largest near the surface of the conductor, decreasing at greater depths. The electric current flows mainly at the "skin" of the conductor, between the outer surface and a level called the skin depth

说明：  这是一个c++实现的基本遗传算法 很好用的，只要按照提示输入数值区间就行了或者自己把那个函数改一下就可以做了。(c++ to achieve a good basic genetic algorithm used)

读取SAR影像的MATLAB编码，非常有用哦！(SAR image of the MATLAB code to read, it is very useful !)

AM RECEIVER based on super heterodyne principle virtually used in all modern radio and television receivers. The approach mainly involves the use of heterodyning or frequency mixing. The signal from the antenna is filtered sufficiently at least to reject the image frequency and possibly amplified. A local oscillator in the receiver produces a sine wave which mixes with that signal, shifting it to a specific intermediate frequency (IF), usually a lower frequency. The IF signals is itself filtered and amplified and possibly processed in additional ways. The demodulator uses the IF signals rather than the original radio frequency to recreate a copy of the original modulation (such as audio). The project is coded in MATLAB.
