Refractive index of cells
WebMar 1, 2024 · Metamaterial absorbers in the terahertz region are highly desirable in sensing and detection. In this work, a novel terahertz refractive index sensor based on metamaterial absorber for sensing biomedical samples is reported. The proposed structure consists of three asymmetrical metallic resonators made of gold placed above on a gallium arsenide … WebThe reflectivity, R, between two materials of different refractive indices is determined by: R = ( n 0 − n S i n 0 + n S i) 2 where n 0 is the refractive index of the surroundings and n Si is the complex refractive index of silicon. For an unencapsulated cell n …
