Abstract :
The electrical characteristics of a short (2 beta lambda =0.4 m) resonator with large modulation (m=4) have been studied using the MAFIA three-dimensional codes. The complete resonator, including the modulated electrodes and a complex support structure, has been simulated using approximately 350000 mesh points. Important characteristics studied include the resonant frequency, electric and magnetic field distributions, quality factor, and stored energy. The results of the numerical simulations are compared with the measurements of an resonator and analytical approximations.<>
