A MATLAB GUI platform for realizing the Radiation pattern of narrowband beamformer with random array geometry. User can specify the array geometry, directions of incoming signals, noise power, and the type of beamformer. Useful for gaining insight about collaborative beamforming in sensor networks and random arrays. You need both randomarray.fig and randomarray.m to work.

随着系统设计复杂性和集成度的大规模提高，电子系统设计师们正在从事100MHZ以上的电路设计，总线的工作频率也已经达到或者超过50MHZ，有一大部分甚至超过100MHZ。目前约80% 的设计的时钟频率超过50MHz，将近50% 以上的设计主频超过120MHz，有20%甚至超过500M。当系统工作在50MHz时，将产生传输线效应和信号的完整性问题；而当系统时钟达到120MHz时，除非使用高速电路设计知识，否则基于传统方法设计的PCB将无法工作。因此，高速电路信号质量仿真已经成为电子系统设计师必须采取的设计手段。只有通过高速电路仿真和先进的物理设计软件，才能实现设计过程的可控性。传输线效应基于上述定义的传输线模型，归纳起来，传输线会对整个电路设计带来以下效应。 · 反射信号Reflected signals · 延时和时序错误Delay & Timing errors · 过冲(上冲/下冲)Overshoot/Undershoot · 串扰Induced Noise (or crosstalk) · 电磁辐射EMI Radiation

Integrated EMI/Thermal Design forSwitching Power SuppliesWei ZhangThesis submitted to the Faculty of theVirginia Polytechnic Institute and State Universityin partial fulfillment of the requirements for the degree of Integrated EMI/Thermal Design forSwitching Power SuppliesWei Zhang(ABSTRACT)This work presents the modeling and analysis of EMI and thermal performancefor switch power supply by using the CAD tools. The methodology and design guidelinesare developed.By using a boost PFC circuit as an example, an equivalent circuit model is builtfor EMI noise prediction and analysis. The parasitic elements of circuit layout andcomponents are extracted analytically or by using CAD tools. Based on the model, circuitlayout and magnetic component design are modified to minimize circuit EMI. EMI filtercan be designed at an early stage without prototype implementation.In the second part, thermal analyses are conducted for the circuit by using thesoftware Flotherm, which includes the mechanism of conduction, convection andRadiation. Thermal models are built for the components. Thermal performance of thecircuit and the temperature profile of components are predicted. Improved thermalmanagement and winding arrangement are investigated to reduce temperature.In the third part, several circuit layouts and inductor design examples are checkedfrom both the EMI and thermal point of view. Insightful information is obtained.
