In this paper, a 3D numerical model of the Cyclotron radio frequency cavity is presented. Simulations include the coaxial sliding shorts, liner vacuum chamber, coupler, trimming capacitor and the Dees structures. CST microwave studio software has been used for numerical computation. RF simulations are mandatory also in order to analyze the field in the beam region and evaluate the impact of different Dees geometry and eventual field asymmetries. Moreover, 3D COMSOL Multiphysics simulations have been carried out in order to couple the electromagnetic field solution to a custom beam-dynamics code developed in Matlab as a future plan. Time evolution of accelerated beam and electromagnetic field make also possible to verify the magnetic field synchronization. Experimental validation of the developed model will be also presented.
