电磁聚焦成象系统中带不饱和磁铁聚焦磁场的约束逆设计

A Constrained Inverse Design of Focusing Magnetic Field with Unsaturated Magnet for Electrostatic and Magnetic Imaging

本文对电磁聚焦成像系统中带不饱和磁铁的聚焦磁场的逆设计进行了探讨,用约束优化方法——内罚函数法来设计能实现给定磁场分布的实际磁聚焦线圈系统。

An inverse design with constrained conditions of focusing magnetic field with unsaturated magnet for electrostatic and magnetic imaging systems has been investigated in this paper. A constrained optimization method called interior penalty function technique has. been introduced and a universal programme has been drawn up. Thus the focusing coil system can be designed practically, and it can produce a series of required magnetic field distributions. Some examples of design and results have been given.
