Human head modelling at microwave frequencies using open-source electromagnetics solver

A computational electromagnetics platform that can be used to study interactions between electromagnetic fields and human tissues is presented. The developed platform uses pre-existing triangle-represented geometry models and associated dielectric properties to create a finite-difference time-domain (FDTD) computation environment beyond the open-source MATLAN toolbox. Compared with most commercial simulation platforms, the presented platform provides a highly-transparent user interface to solve the complex electromagnetic scattering problems with adjustable texture resolution based on the skin depth value. Furthermore, the open-source functions under this platform can be easily integrated with other external MATLAB programs to conduct an algorithm-controlled computational project. As an example of the presented platform, the modelling and simulating of microwave signals propagation and scattering in a realistic human model are explained.
