Simulation of 650 GHz Backward Wave Oscillators

In this acticle the simulation of novel interdigital backward wave oscillators with CST PARTICLE STUDIO® is described. The mutual coupling of the charged particle movement and transient electromagnetic fields is taken into account by a sophisticated Particle in Cell algorithm. The resulting output power is in excellent agreement with theoretical values. Results are presented with the courtesy and permission of Teraphysics Corporation, USA. Read full article..

Periodic Eigenmode Simulation of a Travelling Wave Tube

CST MICROWAVE STUDIO® enables the simulation of periodic eigenmode problems such as Travelling Wave Tubes(TWT). The group velocity and phase dispersion characteristics can be extracted as well as the Pierce Impedance. Read full article..

Klystron Output Resonator - Particle-in-Cell (PIC) Simulation

This article shows the simulation of a klystron output resonator. The simulation was performed using the Particle in Cell (PIC) code of CST PARTICLE STUDIO™. The PIC code is embedded in the transient solver of CST MICROWAVE STUDIO® and benefits therefore from a mature environment. Read full article..
