1. Frequency tunability of axial cavity vircators and double anode vircators
University essay from KTH/Skolan för elektro- och systemteknik (EES)Abstract : This master thesis investigates the possibility of constructing a continu-ously tuneable virtual cathode oscillator (vircator), which can be used as a radiation source in high power microwave susceptibility testing carried out by the electrophysics group at the Swedish Defence Research Agency (FOI). To determine if a vircator can be made continuously frequency tuneable in a 10 %bandwidth around a central frequency lying within the S-band two vircator designs, the first an axial cavity vircator and the second a double anode vir-cator, are evaluated with electromagnetic particle-in-cell simulations using the software Magic3D.
