This paper discusses the design considerations of a 10 GHz helix traveling wave tube using commercial electromagnetic simulation software CST-PIC/MWS. The dispersion characteristics of the TWT have been analyzed by modeling of a single turn electron-free slice in eigenmode solver. The return loss optimization of the input-output couplers is performed by using of transient solver. The complete model has been simulated and analyzed in particle-in-cell solver and the results are presented. © 2011 IEEE.

This paper presents the simulation of a vane-type magnetron using the commercial electromagnetic software Particle-in-Cell (PIC) solver in CST. The magnetron mainly consist of 18 anode vanes without strap. The resonance frequency has been selected in X band since it has a long production history enabling a ready comparison of computed and measured results. Simulation of magnetrons has been improved by changing dimensions of cavities, optimizing voltage and applied magnetic fields values. The aim of this work is to tune the operation frequency of magnetron under the constant electric field and the magnetic field between the anode and . . . cathode. © 2011 IEEE
