The open access journals are scholarly journals of Information Technology Engneering. The top open access journals are freely available on the public internet domain, allowing any end users to read, download, copy, distribute, prink, search or link to the full texts of the articles. These provide high quality, meticulously reviewed and rapid publication, to cater the insistent need of scientific community. These journals are indexed with all their citations noted. The top open access journals are indexed in SCOPUS, COPERNICUS, CAS, EBSCO and ISI. Electromagnetic field (EMF) radiation is very controversial issue. For one hand, many therapeutic and diagnostic applications are proved effective; on the other hand, excessive exposure may cause adverse biological effects. In order to prevent the over-exposure, the worst results are frequently discussed for the safety limits. The basis of the issue is to establish the relationship between the external radiation field and the dose (SAR) distribution in the whole body and the specified tissues. External sources, dosimetric methods and the digital human models are the key elements which could determine that relationship. Because of lack of the non-invasive measurement techniques, numerical methods such as FDTD, FEM and MoM are frequently utilized to qualify the in-body dose distribution. Variability introduced for the numerical methods are insignificant. Given the external radiation field are fixed; the influential factors were include the tissue dielectric properties, postures/statures, anatomical structures, physique features and etc. Practically, they are often interwoven to each other.
