Abstract: Using finite difference time domain(FDTD)method,the model of interaction between mobilephone and human body is established.The values of SAR absorbed by human body and radiation pattern of the antenna are calculated under the irradiation of a mobilephone before and after coating carbon nanotubes (CNTs) composites at 1 800 MHz.The results shows that the use of CNTs composites absorbing material on the mobilephone can obviously reduce SAR values and the antenna performance is less affected.

Key words: radiation of mobilephone, FDTD, SAR, CNTs
