| Abstract: | According to the vector Green formula,the vector integral connection of the magnetic field for every point in the big boundary plane was given,and the relation between the measuring field and the unknown field was obtained.The linear equations were formed by dissecting the boundary plane to get the continuation field.The continuation field could improve the calculation precision of the far field.The experiment proves the validity of the continuation method,which shows that the field of big plane can be obta... |
