Diffraction of a Gaussian beam in a three-dimensional smoothly inhomogeneous medium: an eikonal-based complex geometrical-optics approach.
We present an ab initio account of the paraxial complex geometrical optics (CGO) in application to scalar Gaussian beam propagation and diffraction in a 3D smoothly inhomogeneous medium. The paraxial CGO deals with quadratic expansion of the complex eikonal and reduces the wave problem to the solution of ordinary differential equations of the Riccati type. This substantially simplifies the desc...
متن کاملModified geometrical optics of a smoothly inhomogeneous isotropic medium: the anisotropy, Berry phase, and the optical Magnus effect.
We present a modification of the geometrical optics method, which allows one to properly separate the complex amplitude and the phase of the wave solution. Appling this modification to a smoothly inhomogeneous isotropic medium, we show that in the first geometrical optics approximation the medium is weakly anisotropic. The refractive index, being dependent on the direction of the wave vector, c...
متن کاملA Three Dimensional Alfvénic Pulse in a Transversely Inhomogeneous Medium
Interaction of incompressible and compressible MHD fluctuations on a one-dimensional plasma inhomogeneity, transverse to the magnetic field, is considered in the three-dimensional regime. An initially incompressible (Alfvénic) MHD fluctuation generates, by linear coupling, compressible (magnetoacoustic) fluctuations. In the initial stage of the interaction, the efficiency of the coupling is enh...
متن کاملA Three Dimensional Magnetohydrodynamic Pulse in a Transversely Inhomogeneous Medium
Interaction of impulsively generated MHD waves with a one-dimensional plasma inhomogeneity, transverse to the magnetic field, is considered in the three-dimensional regime. Because of the transverse inhomogeneity, MHD fluctuations, even if they do not include initially any density perturbation, evolve toward states where the compressible components tend to become predominant. The propagating MH...
متن کاملPropagation of a finite optical beam in an inhomogeneous medium.
The first part of this paper is devoted to extending the Huygens-Fresnel principle to a medium that exhibits a spatial (but not temporal) variation in index of refraction. Utilizing a reciprocity theorem for a monochromatic disturbance in a weakly inhomogeneous medium, it is shown that the secondary wave-front will be determined by the envelope of spherical wavelets from the primary wavefront, ...
