ABSTRACT:This paper first introduces the theoretical knowledge about electromagnetic wave; it includes the history of foundation of electromagnetic theory，Maxwell equations, energy of electromagnetic field, boundary conditions of electromagnetic field, electromagnetic spectrum. Second, what is reviewed for near year includes the application of the modern microwave technology and infrared technology, the development of electronic war of modern information, and modern electromagnetic weapons. Third, this part is the discussion about the hazard of electromagnetic wave for human’s body and living environment, and the development of mechanism and materials of shielding of electromagnetic wave. Finally, the necessary for human to strengthen the management of electromagnetic radiation and the consciousness of electromagnetic guard, protect living environment and human’s health is obtained. 

Key word: Electromagnetic weapons; Electromagnetic radiation;Electromagnetic shield
