The eigenfunction of a double entrance cavity is computed by the classical field match method.The result shows that for an entrance cavity with regular drift sp
On the basis of a work of Wu Jianqiang et al.(1987),by making use of the linear kinetictheory,the gyromonotron with a combining periodic magnetic field and a co
The partial charge-simulation method is presented for calculating the capacitances of rectangularshielded lines with offset inner conductors.The capacitances ca
The effects of a beam thickness and a conducting wall in a free electron laser with a linearlypolarized wiggler magnetic field and an axial magnetic field are i
