Coaxial feed structures are widely used in ultra-wide band antennas . This paper modeled the characteristic of the monopole antenna feeded by coaxial line by FDTD in the time-domiain,which showes that . Firstly, it introduced the theory of the arithmetic and the particularly realization in the calculation then it described the use in the time-domain Finally it analysed several characteristics of the monopole antenna. The arithmetic used in the microstrip antenna is also a quick and economical way to design the antenna.

实验12 异常处理 12.1 实验目的 （1）掌握异常处理的编程特点。 （2）了解Java异常分类层次，常见系统异常。 （3）了解自定义异常的定义及方法异常的抛出与处理。 12.2 知识要点 Java把异常加入Java语言的体系结构，为异常定义了类和关键字，简化了错误处理代码。将错误处理从正常的控制流中分离出来，对错误实施统一处理。 12.2.1异常处理结构 try { 语句块； } catch (异常类名1 参变量名) { 语句块； } catch (异常类名2 参变量名) { 语句块； } Finally { 语句块； } 说明： （1）Finally总是执行，它是异常处理的统一出口，常用来实现资源释放，文件关闭等。 （2）发生异常时try块内的后续语句不再执行； （3）catch按照次序进行匹配检查处理，找到一个匹配者，不再找其它；catch的排列要按照先个别化再一般化的次序。不能将父类异常排在前、子类异常排在后。 12.2.2 常见系统异常 常见系统异常如表12-1所示。 表12-1 常见系统异常
