Tapered C-band magnetically insulated line oscillator

Tapered magnetically insulated line oscillator (MILO) was simulated by 2D particle-in-cell (PIC) electromagnetic code. The MILO's parameters for highest output power in C-band was researched. The physics mechanism about tapered MILO was explained. The mechanism shows that under the same conditions, tapered MILO can output higher power than conventional MILOs.
