Keheterogenan tisu kepala yang diperlukan dalam penilaian kadar penyerapan khusus (SAR) puncak spatial untuk telefon mudah alih telah disiasat dengan menggunakan kaedah FDTD bersama-sama dengan model kepala manusia berasaskan MRI. Keheterogenan tisu model kepala telah diubah daripada satu jenis tisu kepada 17 jenis tisu. Keputusan menunjukkan bahawa, pada 900 MHz dan 2 GHz, pemodelan homogen menghasilkan anggaran yang rendah kira-kira 20% untuk telefon mudah alih antena monopole λ/2 dan terlalu tinggi pada tahap yang sama untuk telefon mudah alih λ/4 monopole atau antena heliks. Model kepala dengan struktur kulit-lemak-otot-tulang-otak yang ringkas nampaknya mencukupi untuk mendapatkan purata nilai SAR puncak spatial satu gram atau sepuluh gram yang agak tepat dalam dosimetri pengiraan untuk pematuhan telefon mudah alih.

Abstract: The head tissue heterogeneity required in the spatial peak specific absorption rate (SAR) assessment for portable telephones was investigated by using the FDTD method in conjunction with an MRI-based human head model. The tissue heterogeneity of the head model was changed from one type of tissue to 17 types of tissue. The results showed that, at 900 MHz and 2 GHz, the homogeneous modeling results in an underestimate about 20% for the λ/2 monopole antenna portable telephones and an overestimate to the same extent for the λ/4 monopole or helical antenna portable telephones. A head model with a simple skin-fat-muscle-bone-brain structure seems to be sufficient to obtain a fairly accurate one-gram or ten-gram averaged spatial peak SAR value in computational dosimetry for portable telephone compliance.
