Modeling of Gelatin-Based Head Phantom Based on its Electrical Properties for Wideband Microwave Imaging Application

Abstract

This article presents a human head phantom characterization based on the study of its electrical properties across 1 to 6 GHz. The study focuses on the grey matter, white matter, cerebral spinal fluid (CSF), blood and skin of human head. Through the investigation and study of the human head characteristics, its phantom can be modeled using simple and common materials, which are gelatin, water and sugar. The electrical properties of the chosen mixtures of materials mimicking the electrical properties of human head are measured using special dielectric probe connected to a vector network analyser (VNA). This human head phantom later can be applied in the microwave imaging system for a further study on the health monitoring of human body.
