有限积分理论(FIT)及其在腔体计算中的应用
Finite integral theory and its application on cavity simulation
-
摘要: 通过介绍麦克斯韦方程的离散过程,简单介绍了有限积分理论(Finite Integration Theory)。该理论直接以电场强度和磁感应强度为未知量,采用两套互相正交的网格,将场矢量离散为不同网格点上的一系列分量,将矢量积分方程转化为一组线性方程组。通过对SFC高频腔体模拟的实例,可以看出,此方法在腔体本征频率、Q值及腔体并联阻抗等腔体参数计算中具有叫高的精度,说明了基于FIT的MAFIA程序在腔体模拟中的可靠性。Abstract: Through the descretization of the Maxwell's equations, the general finite integration theory has been introduced. This theory makes direct use of the electric and magnetic field as unknowns, thus yielding uniquely defined vectors in combination with a suitable grid definition. Finially through its reliability on the SFC (Injector Accelerator of HIRFL) resonate cavity, its reliability on cavity simulation has been discussed al so.
