Abstract：
In this paper the performance of a new type (modulating widths type)of linear periodic magnets is analysed.In ideal 2-dimensional case the field produced by this type of magnet is pure sinusoidal.Soft iron shield can be used to strengthen the magnetic field and in some cases the strengthening factor is larger than two.
The expressions of the field distributions in ideal case and in real case and the expression of strengthening factor are given.Methods for reducing undesirable harmonics in the magnetic field are also discussed in this paper.
