Abstract :
From extremely low frequencies to intermediate frequencies, the magnitude of induced electric field inside the human body is used as the metric for human protection. Commonly encountered problems in computational low-frequency dosimetry include slow computation speed and numerical errors caused by the staircase approximation of curved boundaries. This study will first demonstrate that the computational time is no longer a problem. Then, a technique for assessing the effect of the staircasing error is presented.
