Measurement of Blood Glucose Level by Transmission and Reflection of Millimeter Waves

A non-invasive technique to measure blood sugar level is one of the most demanding techniques. In this paper, a new technique is studied to measure blood sugar level by obtaining millimeter wave transmission and reflection coefficients. High sensitivity can be obtained by measuring transmission coefficient, especially by measuring differential transmission. If the reflection coefficient is measured, the system structure becomes simpler. Nevertheless, the sensitivity is usually not so high as comparing to the application of transmission coefficient. To apply resonant metallic fiber on the reflection plane, the sensitivity can be increased. The paper also discusses the increase of the sensitivity to measure the blood sugar level by reflection coefficient using Finite Integration(FI)method. The method studied here will be useful for the noninvasive diagnosis for blood sugar level.
