The Computation of Lower Bounds for the Norm of the Index of Refraction in an Anisotropic Media from Far Field Data

چکیده
We consider the scattering of time harmonic electromagnetic plane waves by a bounded, inhomogeneous, anisotropic dielectric medium and show that under certain assumptions a lower bound on the norm of the (matrix) index of refraction can be obtained from a knowledge of the smallest transmission eigenvalue corresponding to the medium. Numerical examples are given showing the efficaciousness of our estimates.

The Inverse Electromagnetic Scattering Problem for Anisotropic Media ‡
The inverse electromagnetic scattering problem for anisotropic media plays a special role in inverse scattering theory due to the fact that the (matrix) index of refraction is not uniquely determined from the far field pattern of the scattered field even if multi-frequency data is available. In this paper we describe how transmission eigenvalues can be determined from the far field pattern and ...
متن کاملWave Reflection and Refraction at the Interface of Triclinic and Liquid Medium
A Mathematical model has been considered to study the reflection and refraction phenomenon of plane wave at the interface of an isotropic liquid medium and a triclinic (anisotropic) half-space. The incident plane qP wave generates three types of reflected waves namely quasi-P (qP), quasi-SV (qSV) and quasi-SH (qSH) waves in the tric...

متن کاملThe Effects of Openness and Globalization on Inflation: An ARDL Bounds Test Approach
Abstract The purpose of this paper is to test the hypothesis first proposed by Romer (1993); suggesting that inflation is lower in more open economies. According to this hypothesis, central banks have a lower incentive to engineer surprise inflations in more-open economies because the Phillips curve is steeper. Furthermore, Comparing with other empirical studies, this paper has used the new KOF...
متن کاملA Study of Electromagnetic Radiation from Monopole Antennas on Spherical-Lossy Earth Using the Finite-Difference Time-Domain Method
Radiation from monopole antennas on spherical-lossy earth is analyzed by the finitedifference time-domain (FDTD) method in spherical coordinates. A novel generalized perfectly matched layer (PML) has been developed for the truncation of the lossy soil. For having an accurate modeling with less memory requirements, an efficient "non-uniform" mesh generation scheme is used. Also in each time step...
