A meta-material structure which is used to transform electromagnetic energy into a local temperature field is designed. The local electric field enhancement effect of metamaterials can generate strong electric fields and achieve the electromagnetic energy-thermal energy conversion. The electromagnetic wave energy is coupled to the surface of the meta-material through a way of wireless, collecting the wireless energy. The experiments show that the energy of electromagnetic wave can be localized in finite space as heat energy via reasonable structural design. The highest temperature of local temperature field enhancement can reach at 2010 . Through combining with thermo-material Bi2Te3,an energy collector which is used to convert the electromagnet energy into the electric energy is designed. The output voltage of a single structural unit is as high as 27 mV under an incident microwave of 7 W.
