摘要： Magnetic field distributions of a planar pulse microwiggler are studied analytically and numerically. An exact solution of two-dimensional magnetic field is derived in detail,and the formula shows that along the electron axis the field has a variation close enough to a sine wave. Effects of ends of the microwiggler on magnetic field are also investigated with the help of numerical methods.
