Simulation Study on Terahertz Based Cancer Cell Diagnostic System Using COMSOL

Cancer is one of the deadliest diseases in the world [1]. Early detection of cancer is required to reduce the motility rate all over the world [2]. In this paper, diagnostic of cancer using Terahertz (THz) technology have been discussed. Terahertz wave lies between the frequency ranges of 0.1 THz to 10 THz [3]. Simulation model of Terahertz based system for cancer cell detection has been designed using COMSOL software [4]. The simulation has been performed with excitation of frequencies in the range of 0.075 THz to 0.1 THz with step size 0.1 GHz. The simulation studies have been performed by its comparative analysis of reflection and transmission properties of cancer cells and normal cells. The cells have been designed based on their dielectric properties, shapes and sizes. The aim of our study is to distinguish between viable cells and malignant cells from human skin with the help of
$\mathrm{S}_{11}$
and
$\mathrm{S}_{21}$
parameter in COMSOL.
