The problem of modeling the coupling between body mounted antennas is often not amenable to attack by hybrid techniques owing to the complex nature of the human body. For instance, the time-domain Green\u2019s function approach becomes more involved when the antennas are not conformal. Furthermore, the human body is irregular in shape and has dispersion properties that are unique. One consequence of this is that we must resort to modeling the antenna network mounted on the body in its entirety, and the number of degrees of freedom (DoFs) can be on the order of billions. Even so, this type of problem can still be modeled by employing a parallel version of the FDTD algorithm running on a cluster. Lastly, we note that the results of rigorous simulation of BANs can serve as benchmarks for comparison with the abundance of measurement data.<\/jats:p>","DOI":"10.3390\/s120709862","type":"journal-article","created":{"date-parts":[[2012,7,23]],"date-time":"2012-07-23T11:11:45Z","timestamp":1343041905000},"page":"9862-9883","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Electromagnetic Wave Propagation in Body Area Networks Using the Finite-Difference-Time-Domain Method"],"prefix":"10.3390","volume":"12","author":[{"given":"Jonathan N.","family":"Bringuier","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, The Pennsylvania State University, University Park, PA 16802, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raj","family":"Mittra","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, The Pennsylvania State University, University Park, PA 16802, USA"},{"name":"King Fahd University of Petroleum and Minerals, Dhahran 31932, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2012,7,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1269","DOI":"10.1109\/TAP.2010.2096184","article-title":"Analytical propagation modeling of BAN channels based on the creeping-wave theory","volume":"59","author":"Alves","year":"2011","journal-title":"IEEE Trans.
