单片机编程 基于DAC7512的数控直流恒流源设计
为了解决磁放大器性能测试过程中,需要对其供给不同数值恒定电流的问题,设计了一种基于DAC7512和单片机的数控恒流源系统。该系统采用AT89C51作为主控器件,将计算机发送的电流控制字命令转换为D/A转换器控制字,通过模拟SPI通信接口,写D/A控制字到DAC7512,从而控制其输出相应数字电压值,经差动缩放电路、电压/电路变换 ...

文章/文档 In an electromagnetic cloak based on a transformation approach, reduced sets of material properties
In an electromagnetic cloak based on a transformation approach, reduced sets of
material properties are generally favored due to their easier implementation in reality,
although a seemingly inevitable drawback of undesired reflection exists in such cloaks.
Here we suggest using high-order transforma ...

Feeding antennas with proper signals can be difficult. The signal is often described as a voltage, and voltages are not well defined in electromagnetic wave formulations. There are several tricks to model voltage generators in such situations, and one is the magnetic frill. This model shows the basi ...
