A Numerical Study on EM Interaction of a Multilayered Superquadric-Ellipsoidal Head Model and MRI-Based Heads Proximate to a Dipole Antenna at 900/1800 MHz

摘要

A multilayered superquadric-ellipsoidal head model is proposed to evaluate the EM interaction of the human head with a dipole antenna. The SAR distribution among the head model is computed by using the FDTD method. The SAR distribution and antenna radiation characteristics affected by different thicknesses of the fat layer are also studied. For EM exposure assessment measurement, the proposed head model provides a flexible and feasible solution.
