Eikonal Method in Magnetohydrodynamics

Physical Review, 1962
The eikonal method is extended to waves with several components propagating in inhomogeneous anisotropic media. Formulas are derived for the motion of wave packets, the change in amplitude along a ray path, and the corrections due to diffraction. The method is applied to pure magnetohydrodynamic disturbances, and the problem of computing ray paths in ...

On the eikonal function

Radio Science, 1996
A survey of the various mathematical derivations of the eikonal equation of Bruns is given, each having its own geometrical approximation. These include the Sommerfeld‐Runge ansatz and the variational principle applied to the action integral. The apparent arbitrariness of the ansatz is justified by its giving the same form of eikonal equation as does ...

Iconoclast and Eikon

1990
From Bertrand Russell, Portraits from Memory and Other Essays (London: George Allen & Unwin, 1956) pp. 71–5, 100. Despite his claim to have first met Shaw at the 1896 International Socialist Congress (held in St Martin’s Hall, London, between 28 July and 1 August) there was an earlier meeting when they were on holiday with the Webbs in Monmouth in ...
