Major Research Domain:
Biomedical Applications of sub-Terahertz Waves
Details:
The goal of my current research is to discover various biomedical applications for sub-terahertz sensors. In comparison to infrared-based spectroscopy, the main advantage of using this band is that it suffers less scattering by water constituents inside the tissue, increasing the wave's penetration depth. Aside from this, sub-terahertz measurement systems have superior sensitivity and resolution to microwave-based measurement systems. Non-invasive blood glucose measurement and tumor margin assessment during tissue conserving surgery are two interesting applications of the sub-terahertz band that I have studied in this direction.
In the first application, blood tissue has been characterized in this band using different glucose solutions using the double Debye model. The difference in permittivity for different glucose concentrations in the sub-Terahertz band has been used to develop a non-invasive blood glucose measurement system.
The electronic sub-terahertz waveguide iris probe sensor system has been developed for the second application to identify positive and negative margins during tissue conserving surgery. This imaging system can replace time-consuming biopsy procedures during intraoperative surgical procedures. This sensor system is also less expensive and less bulky than the photonics-based terahertz systems currently under investigation for this application. This imaging system can be used during intraoperative surgical procedures which can replace the time taking biopsy procedures. In addition, this sensor system is in-expensive and less bulky as compared to the photonics based terahertz systems currently researched for this application.
Along with these biomedical applications, a new robust method for other low loss material characterization has also been devised which uses RMS delay propagation in Fresnel's Region to estimate the permittivity of the unknown dielectric sample.
