Frame-dragging effect manifests itself as polarization direction rotation when linearly polarized electromagnetic/gravitational wave scatters from a spinning point source through gravitational interactions, an also known the Faraday rotation. Treating general relativity effective field theory, angle and its quantum corrections are computed using scattering amplitudes. While classical is univers...
electromagnetic waves can damage sex organs and cause hormonal disorders, and garlic isknown to reduce risk factors for various diseases. the aim of this study was to investigate theprobable effects of mobile phone radiation and the consumption of garlic on testosterone levelsand testicular changes. five groups of rats were used: control, sham (exposed to 900 mhzwavelength), experimental group ...
We inspect the optical properties of dissipative double-negative metamaterials (DNMM) and find explicit expression for total reflection angle correct Fresnel formulae describing refraction DNMM at oblique incident electromagnetic wave on interface \textit{TE} as well \textit{TM} polarization. The reflectivity transmissivity film embedded in a positive index (PIM) surrounding are presented discu...
Coherent excitation and control of lattice motion by electromagnetic radiation in optical frequency range has been reported through variety of indirect interaction mechanisms with phonon modes. However, coherent phonon excitation by direct interaction of electromagnetic radiation and nuclei has not been demonstrated experimentally in terahertz (THz) frequency range mainly due to the lack of THz...
A theory of auroral kilometric radiation due to the nonlinear interaction between negative energy electromagnetic waves and coherent electrostatic ion cyclotron waves is developed. The theory predicts that such radiation produced must have X mode polarization and must have a frequency that lies in a narrow band between the right-hand cutoff and the Doppler-shifted beam cyclotron frequency for e...
We consider a p-polarized surface electromagnetic wave (a classical surface polariton) at the interface between the vacuum and a metal or left-handed medium. We show that the evanescent electromagnetic waves forming the surface polariton inevitably possess a backward spin energy flow, which, together with a superluminal orbital energy flow, form the total Poynting vector. This spin energy flow ...
We employ a homogenization procedure to describe the propagation of electromagnetic waves in a dielectric structure which is doubly-periodic in the X-Y plane and of arbitrary variation in the direction of propagation, Z. The fundamental cell is composed of an arbitrarily shaped pore filled with a dielectric and the host by another. Our analysis yields the structure of the electromagnetic fields...
Polarization-transfer components for He(~e, e~ p)H are computed within the relativistic multiplescattering Glauber approximation (RMSGA). The RMSGA framework adopts relativistic singleparticle wave functions and electron-nucleon couplings. The predictions with free and various parametrizations for the medium-modified electromagnetic form factors are compared to the world data. In conventional n...
A theoretical description of nucleon knockout reactions initiated by polarized electron scattering from polarized nuclei is presented. Explicit expressions for the complete set of reduced response functions (independent of the polarization angle) that can be experimentally obtained assuming plane waves for the electron are given in a general multipole expansion. The formalism is applied to the ...
The application area of optical fibers is quite extensive. Telecommunication applications were the primary field of fibers employment. The related area is the utilization of optical fibers for control purposes, which benefits from principal galvanic isolation between the transmitting and receiving part of the system. A minimal sensitivity of light propagation inside the fiber to electromagnetic...
