摘要

本論文利用時域有限差分法模擬均勻與非均勻人體模型曝露在頻率1869 MHz手機基地臺之足部感應電流。 亦同時利用平行板電流儀去測量人體曝露於手機基地臺在1869MHz時所感應的人體電流。 從時域有限差分法模擬結果發現採用非均勻人體模型比採用均勻人體模型所獲得的足部感應電流稍為小。 數值計算之結果亦與利用平行板電流儀去測量人體足部感應電流作比較，比較中發現兩種模型所獲得的足部感應電流值均與平行板電流儀所量測到的足部感應電流值的資料相當接近。

The finite-difference time-domain (FDTD) method is used to calculate the induced foot currents in homogeneous and inhomogeneous human models exposed to cellular phone base stations at 1869MHz. Currents induced in human feet near a cellular phone base station were measured by a parallel plate meter at 1869MHz. From simulation results by using the finite-difference time-domain (FDTD) method, currents induced inside inhomogeneous human models have only a slight amount less than those obtained inside homogeneous models. Numerical results of induced foot currents are compared with measurement data obtained by a parallel plate current meter. From study results, it is shown that simulation results for both homogeneous and inhomogeneous models make good agreement with those measured by experiments.
