This paper presents a numerical-experimental validation of a finite-difference time-domain code employing a graded-mesh (GM-FDTD). To this aim, a prototype of a mobile phone (mock-up), equipped with a helical antenna, is manufactured and modelled using the GM-FDTD code and a freeware code based on the method of moments (MoM). The return loss (RL), together with the near electric- and magnetic-field distributions, have been computed using the GM-FDTD code and compared with the MoM results and measurements. Moreover, the specific absorption rate (SAR) induced by the phone inside a cubic phantom has been measured and evaluated with the GM-FDTD code. The agreement between the numerical and experimental results is within acceptable measurement uncertainty. © 2005 Wiley Periodicals, Inc.
