Propagation of a slightly diverging Gaussian beam in a gyrotropic medium [constitutive equation (1.1)] across the gyration vector g is considered. The polarization, phase, and geometrical features of the beams are elucidated. For a sufficiently small gyrotropy, the medium deflects the beams like ...

Based on the ABCD matrix, we obtain the field distributions both inside and outside the LHM slab, and the conditions for focusing and phase compensation of the Gaussian beam. Secondly, the derived ABCD law is applied to analyze the propagation properties of Gaussian beams through various cascaded...

We present a new beam propagation method, which circumvents these difficulties. The idea is to decompose the beam as a product of a Gaussian Beam TEM00 and an unknown distortion function Ξ. This leads to an interesting partial differential equation for Ξ, which contains a beam spreading ...
The propagation of a Gaussian beam through an asymmetric optical system results in a generally or "twisted"" astigmatic beam whose elliptical spot rotates as it propagates in free space. A general mathematical form for this beam is derived by applying the angular spectrum approach to the paraxial...
Taking the Gaussian background vortex beam with topological charge +2 as a typical example, a closed-form expression for vortex Gaussian beams passing through a half-plane screen is derived and used to study the propagation dynamics of on-axis and off-axis vortex diffracted beams, and to compar...
Non-paraxial propagation of standard Hermite-Gaussian-beams is investigated by the expansion theory introduced by Lax et al. [Phys. Rev. A 11 (1975) 1365]. The results of the expansion theory applied to Hermite-Gaussian-modes with complex arguments by Takenaka et al. [J. Opt. Soc. Am. ...
