The amount of this energy absorbed by the human head is measured by the specific absorption rate (SAR). There are standard limits, according to which phones sold should be below certain SAR level. To maintain these limits, shields can be used for the mobile phones. In this paper using ANSYS HFSS, modelling of the human head is done. The modern mobile phone design is used for simulation. SAR distribution is measured for different layers of the head due to exposure to radiation from the mobile phone operating at GSM-1800 frequency band. The performance of the mobile phone antenna due to different shields is observed. Proper shielding material properties are found.<\/jats:p>","DOI":"10.1186\/s13673-016-0059-0","type":"journal-article","created":{"date-parts":[[2016,4,4]],"date-time":"2016-04-04T11:38:25Z","timestamp":1459769905000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["SAR reduction in the modelled human head for the mobile phone using different material shields"],"prefix":"10.1186","volume":"6","author":[{"given":"Prabir Kumar","family":"Dutta","sequence":"first","affiliation":[]},{"given":"Pappu Vankata Yasoda","family":"Jayasree","sequence":"additional","affiliation":[]},{"given":"Viriyala Satya Surya Narayana Srini","family":"Baba","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2016,4,11]]},"reference":[{"issue":"04","key":"59_CR1","doi-asserted-by":"publisher","first-page":"44","DOI":"10.9790\/3021-04464449","volume":"04","author":"VB Kumar","year":"2014","unstructured":"Kumar VB, Gopi V, Jayasree PVY (2014) Evaluation of electromagnetic absorption in human head from mobile phones.
