研究目的
To calculate the exact magnetic field required in high power microwave generation using Backward Wave Oscillator (BWO) to increase the efficiency of the device by replacing electromagnets with permanent magnets.
研究成果
The derived expressions allow for the calculation of the exact value of axial magnetic field for a desired frequency, considering parameters like SWS dimensions and beam voltage. This is the first time such a comprehensive relation has been established, showing good agreement with experimental data.
