Dynamic raytracing in inhomogeneous anisotropic media
I present a new differential equation system for dynamic raytracing in inhomogeneous anisotropic media. This new system is computationally much more efficient than the traditional elastic-parameter based system as the right-hand-side functions of this new system are simple. Evaluation of these functions involves only differentiation of phase velocities. Evaluation of the right-hand-side functio...
متن کاملRay-Optics Analysis of Homogeneous Uniaxially Anisotropic Media
In this report, we introduce a model based on geometrical optics which describes the propagation of light in homogeneous uniaxially anisotropic media. We call this model the OpIn model. A ray-tracing algorithm based on the OpIn model is also introduced. Results from a test case obtained by the OpIn model are compared with results from the commercial ray-tracing program ASAP. It appears that res...
متن کاملA 3D porous media liver lobule model: the importance of vascular septa and anisotropic permeability for homogeneous perfusion.
The hepatic blood circulation is complex, particularly at the microcirculatory level. Previously, 2D liver lobule models using porous media and a 3D model using real sinusoidal geometries have been developed. We extended these models to investigate the role of vascular septa (VS) and anisotropic permeability. The lobule was modelled as a hexagonal prism (with or without VS) and the tissue was t...
متن کاملExperimental Investigation of the Permeability and Inertial Effect on Fluid Flow through Homogeneous Porous Media
The value of the permeability in fluid flow through porous media is important for process investigation. In low Reynolds number, the classic Darcy’s law is suitable for simulation of fluid flow. In this paper, an experimental study for evaluation of preformed fiber permeability has been done. Also, the deviations from the classical Darcy law by experimental and numerical simulation of the N...
متن کاملSimulation of Ultrasonic Continuous Wave Fields in Homogeneous Media with Soft Curved Interfaces
This work presents an acoustic field simulation method derived from the Green’s functions based monochromatic solutions of the wave equation in homogeneous media. Following this approach, for a given emitting aperture and for an arbitrary set of target points, it is possible to define a spatial monochromatic transfer matrix (MTM). The amplitude and phase of the acoustic field at the target poin...
