One of its peculiar features is that the magnetic dipole mode is tilted with respect to the planetary rotation axis by only ≈0.007° or less. Numerical dynamo simulations performed in this context have had great difficulty in …
WebbA paraxial ray is a ray which makes a small angle ( θ) to the optical axis of the system, and lies close to the axis throughout the system. [1] Generally, this allows three important approximations (for θ in radians) for calculation of the ray's path, namely: [1] The paraxial approximation is used in Gaussian optics and first-order ray ... Webb22 sep. 2009 · In this chapter we assume that the angles between the rays and the axis are so small that the images formed are essentially perfect. The resulting approximate theory of lenses is called the paraxial approximation, or Gaussian optics. We use in this chapter an abstract method based on eikonal function theory.
WebbThe small-deformation theory (or, equivalently, the small-strain or infinitesimal theory) is customarily obtained by assuming that the displacements u are small, and expanding u in a power series with respect to a small parameter. 12 As a consequence of this approximation, ( 3.7 ), ( 3.27 ), ( 3.36 ), ( 3.54 ), and ( 3.55) become, to leading ...
