| Abstract: | In this paper ,a study is made of the application of severaldifferent energy - density expressions in some typical cases. Starting from the theorem of Maxwell electromagnetic field , the paper reaches the conclusion that only Poynting vector can fully and correctly reflect the conversion and spread of electromagnetic energy. |
