چکیده

This report presents the polarizability matrix of a tri-isotropic sphere. A tri-isotropic material exhibits coupling between electric, magnetic, and in addition, a third kind of material response. Each of these three fields creates three different kind of polarizations. The paper derives the polarizability components of such a sphere in vacuum and makes physical interpretations of the results for the copolarizabilities and cross polarizabilities.

Perturbative Approach to Calculating the Correlation Function of bi-isotropic Metamaterials

A bi-isotropic magneto-electric metamaterials is modeled by two independent reservoirs. The reservoirs contain a continuum of three dimensional harmonic oscillators, which describe polarizability and magnetizability of the medium. The paper aimed to investigate the effect of electromagnetic field on bi-isotropic. Starting with a total Lagrangian and using Euler-Lagrange equation, researcher cou...

On the Estimation of Excited-State Dipole Moments from Solvatochromic Shifts of Absorption and Fluorescence Spectra

The effect of the solvent polarity parameters f (e, n) and j (e, n) appearing in solvatochromic theories, and the effect of the molecular shape of the Onsager cavity (sphere, ellipsoid of revolution) on the determined electric dipole moments me in the singlet excited state are studied. It is found that the shape of the solute does not exhibit a significant effect on the determined values of me,...

In this study, thermal Casimir-Polder potential is calculated for an atom in the presence of a dielectric sphere using the formula given in terms of the Green’s function. Then, the limiting cases of large and small sphere are investigated. In the limiting case of a large sphere, the formula of thermal potential for an excited atom in the presence of a dielectric half-space and then a perfectly ...

Solvent structural relaxation dynamics in dipolar solvation studied by resonant pump polarizability response spectroscopy.

Resonant pump polarizability response spectroscopy (RP-PORS) was used to study the isotropic and anisotropic solvent structural relaxation in solvation. RP-PORS is the optical heterodyne detected transient grating (OHD-TG) spectroscopy with an additional resonant pump pulse. A resonant pump excites the solute-solvent system and the subsequent relaxation of the solute-solvent system is monitored...

Depolarization ratio of Rayleigh scattered radiation by molecules.

The depolarization ratios of Rayleigh scattered radiation by molecules has been used to measure the ratio of anisotropic polarizability to isotropic (average) polarizability in the laboratory. The authors have calculated the depolarization ratio for N2, CH3Cl, and H2O from the first principles. It is shown that the depolarization ratio derived from input polarizabilities differs by a factor of ...
