Based on light ray theory, the Gauss beam lens conversion model is established and the outgoing beam of the tapered-platform fiber end-face is analyzes.
Many analyses using teleseismic body waves were based on the ray theory because of the very efficiently computable direct P-, S-, and major reflected waves near the source.
Many analyses of teleseismic body waves with short periods (in seconds) were based on the ray theory (e.g., Kikuchi and Kanamori [2003]) because of very efficiently computable direct P, S, and major reflected waves near the source.
The simulation is based on ray-tracing techniques and on the X-ray attenuation law.
Liu and Tripathi [7] also observed the self-defocusing of Gaussian beam based on the paraxial ray theory in tunnel ionized neon plasma.
The theory itself is based on the classical ray theory, which yields a quick computational scheme.
Kumar and Tripathi [6] observed the self-defocusing of Gaussian laser pulse based on the paraxial ray theory in tunnel ionized helium plasma.
The second method, based on geometric acoustics ray theory, is designed for large scale sources which may generate non-uniform reverberant fields.
Models are based on different theories: ray theory, parabolic equation modeling, normal mode models, and spectral integral models [1].
Intervention components were based on the Integrative Theory, Protection Motivation Theory, and Self-Determination Theory as previously described [ 24].
