Abstract: Homogeneous metallic waveguides have long been used to carry high powers. They are often filled with inhomogeneous, isotropic dielectrics to reduce their size and cut-off frequencies. To characterize these inhomogeneous rectangular waveguides made of homogeneous and isotropic media, the Newton-Raphson method is used in this article. Frequency of cu... Show More

Abstract: In the present paper, a study and design is presented of a High Sensitivity Terahertz Metamaterial Biosensor for the detection of multiple viruses using the photosensitive semiconductor GaAs. The biosensor comprises a layered structure: a semiconductor GaAs layer at the top, a gold (Au) conductor layer in the middle, and a polyimide substrate at th... Show More
