/ 机械工业出版社
本书前两版为平面微带天线设计人员编写,这一版在前两版的基础上进行了扩展,新增了该领域最新的研究成果,例如:为利用全波分析软件HFSS进行更精确的建模,对铜导体内部的场进行了计算,对四分之一波长微带天线的阻抗带宽与相对介电常数之间的关系进行了更彻底的研究;介绍微带阵列中串联/并联馈电结构;指出常见教科书中设计的几何图形限制天线固有阻抗带宽的问题等。既提供了简单实用、可制造的天线设计实例,又提供了其他参考资料,方便读者研究更复杂的设计。同时考虑了商业应用,是天线工程师了解天线领域前沿技术的极佳参考。

本书介绍对现代体系结构的编译器进行优化的方法,理论基础是基于循环依赖的。分析基于依赖的变换的正确性论述和依赖测试的详细过程。剖析怎样扩展依赖去处理循环嵌套中的流以及跨越整个程序的过程。本书还讨论怎样能用依赖来回答现代计算机系统编译中的众多重要问题,包括支持不同类型体系结构(例如,向量、多处理器、超标量)的并行化,存储层次结构的编译器管理,带指令级并行性的机器的指令调度。,介绍一些不大为人熟知的应用,如硬件设计、数组语言实现以及消息传递系统的编译。
