A 6-mmresolution 7-tissue (skin, blood, bone, muscle, graymatter, white matter, air) anatomy based model (62x62 cells) cross section ofhumanheadisstudied. Fourdipoles ofa 64MHzisapplied. A Neuro-Fuzzy modeling oftheheadispresented. A system that describes input-output behavior inawaysimilar- tomathematical mapping without involving differential operator orequation iscalled astatic system. Thecell size ofstudying domain size is6mmX6mmwidth with2-Dimension formula ofFDTDmethod considering theYee Algorithm. Thecalculated SARinside themodelusing Transparent Absorbing Botiindary Condition (TAB)method forreflection truncation isused todevelop theNeuro-Fuzzy system tobuild upafuzzy inference system (FIS). Amathematical representation ofphysical system (biological model) isusedtodesign applicators toachieve adesired pattern inside themodel. Calculating theSARatthemodel central axis atdifferent phases ofexcitation will bedone, thenumber ofcalculated patterns is39trials. Thisdata isfedtotheintroduced modeling system toclassify theinputs togetasetofclusters inorder todetermine thenumber ofthe rules representing themodel.
