Finite integral theory and its application on cavity simulation

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.
