Depolarization of Electromagnetic Waves By Sea Surface
An improved Two Scale Model (TSM) has been investigated for the depolarization of electromagnetic waves from sea surface. Classical TSM produce depolarized results due to the tilt of reflecting plane. To include the contribution of actual phenomenon we add the second order scattering effects at small scale and develop an improved TSM. Numerical results are obtained for both backscattering and b...
متن کاملOptical surface waves supported and controlled by thermal waves.
We address the formation of optical surface waves at the very edge of semiconductor materials illuminated by modulated light beams that generate thermal waves rapidly fading in the bulk material. We find families of thresholdless surface waves existing owing to the combined action of thermally-induced refractive index modulations and instantaneous Kerr-type nonlinearity.
متن کاملPlane Waves with Negative Phase Velocity in Isotropic Chiral Mediums
The propagation of plane waves in an isotropic chiral medium (ICM) is investigated. Simple conditions are derived — in terms of the constitutive parameters of the ICM— for the phase velocity to be directed opposite to the direction of power flow. It is demonstrated that phase velocity and power flow may be oppositely directed provided that the magnetoelectric coupling is sufficiently strong.
متن کاملSurface waves supported by thin - film / substrate interactions
A systematic approximation to the linear equations for small-amplitude surface waves in an elastic half space, interacting with a residually-stressed thin film of different material bonded to its plane boundary, is developed in powers of the film thickness, assuming the latter to be small compared to the wavelength of the disturbance. The theory is illustrated by calculating asymptotic expansio...
متن کاملFeatures of Electromagnetic Waves Scattering by Surface Fractal Structures
Accurate measurement of surface roughness of machined workpieces is of fundamental importance particularly in the precision engineering and manufacturing industry. This is mainly due to the more stringent demand on material quality as well as the miniaturization of product components in these industries [1-3]. For instance, in the disk drive industry, to maintain the quality of the electrical c...
