The concept of polarization is a method of understanding plane electromagnetic waves geometrically. However, there has been little study of methods of obtaining a general complicated image of electromagnetic field structure such as the near field. In this article, electromagnetic energy parameters of several vector quantities with a dimension of electromagnetic energy flux, such as the Poynting flux, are proposed. By means of these parameters, the field structure is geometrically represented and the image is given. In the representation process, the Rumsey field decomposition is used. The image of the circularly polarized field obtained in this process has not been clearly understood. The nature of this field is characterized in this article from the standpoint that the field has common planes of the polarized ellipse of the electric field and of that of the magnetic field and that their polarization ellipses are similar (similarly polarized fields).
