A high-resolution realistic human head model for the human exposure assessment of the specific absorption rate (SAR) is presented in this article. To our best knowledge, this model is the first Chinese electromagnetic (EM) human head model (CMODEL). The model is built using the first Chinese Visible Human (CVH) data set containing 3,640 serial axial anatomical images. In particular, the model has...
Effects of ground plane on the Specific absorption rate (SAR) in SAM head model exposed PIFA antenna is investigated in this paper. The dual-band PIFA working at 900M and 1800M is designed to operate with a ground plane, and the ground plane is an integral part of the antenna assembly. To investigate systematic biases on SAR in SAM head model resulting from shape effect of the ground, both the average...
With the rapid progress of electronic and information technology, body area network (BAN) has been widely used for biomedical monitoring systems using the human body as a transmission medium. In this paper, the effect of the type of arm models on electric field distribution and attenuation constant of on-body transmission have been investigated. In order to assess the sensitivities of the transmission...
The special absorb rate (SAR) calculation in a layered prolate head model exposed a wire model handset antenna model is investigated using null field method (NFM). NFM is used to solve the scattering problem from the layered prolate head model, and analytical technique is use to obtained current distribution on the thin wire handset antenna. The coupling between the head model and handset antenna...
The electromagnetic radiation of a handset antenna operating in the vicinity of a prolate head model is investigated by NFM and an approximated antenna model. The analytical solution of NFM offers a nearly real time estimation of the SAR value regarding a handset antenna design. Numerical results show the accuracy and efficiency of the proposed quick simulation approach.
The head of the user of a mobile telephone is modeled by a two-layered prolate excited by the near field of a patch antenna. A hybrid null field method/method of moments (NFM/MoM) numerical method is investigated in this paper. NFM is used to solve the scattering problem from the head model, and the MoM using the Rao-Wilton Glisson (RWG) basis functions is applied to model the dipole antenna by distributing...
