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.

實驗12 異常處理 12.1 實驗目的 （1）掌握異常處理的編程特點。 （2）了解Java異常分類層次，常見系統異常。 （3）了解自定義異常的定義及方法異常的拋出與處理。 12.2 知識要點 Java把異常加入Java語言的體系結構，為異常定義了類和關鍵字，簡化了錯誤處理代碼。將錯誤處理從正常的控制流中分離出來，對錯誤實施統一處理。 12.2.1異常處理結構 try { 語句塊； } catch (異常類名1 參變量名) { 語句塊； } catch (異常類名2 參變量名) { 語句塊； } Finally { 語句塊； } 說明： （1）Finally總是執行，它是異常處理的統一出口，常用來實現資源釋放，文件關閉等。 （2）發生異常時try塊內的后續語句不再執行； （3）catch按照次序進行匹配檢查處理，找到一個匹配者，不再找其它；catch的排列要按照先個別化再一般化的次序。不能將父類異常排在前、子類異常排在后。 12.2.2 常見系統異常 常見系統異常如表12-1所示。 表12-1 常見系統異常
