چکیده
In this paper we determine a formula for calculating the refractive index n for the acoustic equation from the partial Dirichlet to Neumann map(DN) associated to n. We apply these results to identify locations and values of small volume perturbations of this refractive index at fixed frequency ω.

Using the eigenvalues of the sound equation to determine the properties of materials
In this article, the eigenvalues of the sound equation are used to determine the refractive index. This refractive index helps to extract the acoustic components of the material such as the speed of sound in the material. This will help in identifying targets, especially in the field of signal processing. For this purpose, a method has been extracted that can be used to establish a relation bet...
متن کاملModeling of Refractive Indices for Binary Aqueous Solutions of Some Alkane Polyols at Constant Temperature and Pressure
In this research, a theoretical study has been undertaken on the density and also on the relationship between refractive index and density for aqueous solutions. A simple linear equation is suggested to show this relationship. Also, a semi-empirical equation has been developed for estimating the constant of this linear equation. By using our suggested equations, the refractive indices of aq...
متن کاملTheoretical Calculations of Refractive Index of Synthesized One and Two Substituted Derivatives of Functionalized Bithiophene Compounds
In order to study the variation of electronic properties, a set of bithiophene derivatives has been developed. Here, the effect of substitution on the aromaticity properties of some cyclic bithiophene derivative compounds was investigated using theoretical calculations. Calculations were performed at B3LYP/6-31+G (d,p) level; and calculated properties included energy, dipole moment, total c...
