Microwave Power Absorption in Human Body for Non-invasive Glucose Monitoring

The main objective of this contribution is to explore the absorption of electromagnetic microwaves in different human body regions for non-invasive glucose monitoring (NGM). Recently, the use of dielectric measurements for the purpose of NGM has been an area of much interest. However, currently no existing report can explore the power dissipation of electromagnetic waves for the NGM. This work is based on established empirical models of human tissue and standard human body models of the Electromagnetic (EM) simulation tools, such as CST Voxel Model. The Specific Absorption Rate (SAR) is investigated for various frequencies and different regions of the human body to estimate the optimum real-world scenarios for non-invasive glucose monitoring (NGM). Empirical models of dielectric properties for estimating the blood glucose concentrations are applied at frequency range from 1 GHz to 10 GHz and blood glucose concentration of hyperglycemia (300 mg/dl), hypoglycemia (40 mg/dl) and euglycemic (100 mg/dl). A comparative evaluation of SAR measurements for blood in free space and blood in body's vessels is presented in context of investigating the effect of power dissipation for dielectric NGM measurements.
