Due to Huygens’ principle the field outside of the surface surrounding field sources (or in the half-space free of sources) can be controlled not only via changing the sources, but also by a proper engineering of the tangent fields. For given sources one may be interested in a design of...
Our aim is a unification of Etter theory, Kron's method of Tearing and Jessel's formulation of Huygens' Principle. This should make explicit the equivalence between the objective, structural, holographic and the subjective, relative definitions of information, sought in Bowden (1994b), reprinted ...

Huygens' Principle (1678) implies that every point on a wave front serves as a source of secondary wavelets, and the new wave front is the tangential surface to all the secondary wavelets. But two problems arise: portions of wavelets that exist outside o
Finally, we prove a Huygens principle for KPP equations on complete riemannian manifolds without cut locus, with some bounds on their volume element, in ... KD Elworthy,A Truman,HZ Zhao,... - 《Proceedings of the Royal Society A Mathematical Physical & Engineering Sciences》 被引量: 25发表...
Christiaan Huygens is best known for devising the principle that bears his name, namely Huygens’ principle (or Huygens’ construction). Huygens’ principle appeared in Huygens’ classic book Traité de la Lumière.
Huygens’ principle, a statement that all points of a wave front of sound in a transmitting medium or of light in a vacuum or transparent medium may be regarded as new sources of wavelets that expand in every direction at a rate depending on their veloci
"Playing with Physics" apps allow interactive simulation of select physics phenomena. The "Huygens' Principle" makes it possible to represent waves in an isotropic environment, i.e. in an environment in which the waves propagate in all directions at t
摘要: A new class of linear second order hyperbolic partial differential operators satisfying Huygens' principle in Minkowski spaces is presented. The construction reveals a direct connection between Huygens' principle and the theory of solitary wave solutions of the Korteweg–de Vries equation....
The wire/loop unit cell naturally synthesizes a Huygens’ source, as it directly realizes the electric and magnetic currents stipulated by the equivalence principle. As was shown in Ref. [66], the equivalent circuit of the wire/loop unit cell is of the lattice topology, as shown in Figure ...
