Gaussian-beam propagation in generic anisotropic wave-number profiles.
The propagation characteristics of a scalar Gaussian beam in a homogeneous anisotropic medium are considered. The medium is described by a generic wave-number profile wherein the field is formulated by a Gaussian plane-wave distribution and the propagation is obtained by saddle-point asymptotics to extract the Gaussian beam phenomenology in the anisotropic environment. The resultant field is pa...
متن کاملGaussian Beam Propagation
Gaussian beams play such an important role in optical lasers as well as in longer wavelength systems that they have been extensively analyzed, starting with some of the classic treatments mentioned in Chapter 1. Almost every text on optical systems discusses Gaussian beam propagation in some detail, and several comprehensive review articles are available. However, for millimeter and submillimet...
متن کاملTorsional Surface Wave Propagation in Anisotropic Layer Sandwiched Between Heterogeneous Half-Space
The present paper studies the possibility of propagation of torsional surface waves in an inhomogeneous anisotropic layer lying between two heterogeneous half-spaces (upper and lower half-space). Both the half-spaces are assumed to be under compressive initial stress. The study reveals that under the assumed conditions, a torsional surface wave propagates in the medium. The dispersion relation ...
متن کاملLaser and Gaussian Beam Propagation and Transformation
Optical engineers and researchers working on optics deal with laser beams and optical systems as usual tools in their specific areas. The knowledge of the special characteristics of the propagation of laser beams through optical systems has to be one of the keystones of their actual work, and the clear definition of their characteristic parameters has an important impact in the success of the a...
متن کاملEulerian Gaussian Beam Method for High Frequency Wave Propagation in the Reduced Momentum Space
Eulerian Gaussian beam method is an efficient way to compute high frequency wave propagation, which was originally studied in [S. Leung, J. Qian and R. Burridge, Geophysics, 72 (2007), pp. 61–76]. Later Jin, Wu and Yang developed a new way of computing the Hessian functions from the derivatives of the level set functions in [S. Jin, H. Wu and X. Yang, Commun. Math. Sci., 6 (2008), 995–1020], wh...
