Abstract :
This work presents a fast volume integral equation solver named the mixed order BCGS-FFT method for electromagnetic simulations of high resolution human bodies with both dielectric and magnetic susceptibility contrasts in MRI application. The mixed order BCGS-FFT method is an accurate and efficient solver developed for magnetodielectric objects. A numerical calculation of the electromagnetic responses of a high resolution voxel human head model shows a high efficiency of the mixed order BCGS-FFT method in both computational complexity and memory requirement.
