At the base of the hierarchy, you have a regular hyperbolic pde on the body without any super information entering into it, and it is only this equation that controls the speed of propagation and hence the huygens' principle. This approach was pioneered by choquet-bruhat in the seminal paper.

There is no proper transformationlal mechanism that ensures this has been done correctly. Normans course on hyperbolic geometry goes into detail about this kind of set up, and it is not trivial, nor impossible. The additonal principle added by fresnel also needs to be examined closely.
Huygens' principle (hp) is understood as a universal principle governing not only the propagation of light. According to hadamard's rigorous definition, hp comprehends the principle of action-by-proximity (cf faraday's field theory etc) and the superposition of secondary wavelets (huygens' construction).

Huygens was a polymath almost without equal, credited with discovering the rings of saturn, the moon titan, the invention of the pendulum clock and groundbreaking studies on optics and centrifugal forces, this study goes beyond these discoveries to find out more about the man and what made him strive to know more.
New results on group theoretical aspects of the huygens principle are presented. An extension of darboux-lagnese-stellmacher’s transformation to the wave equations in spaces with non-trivial conformai group is considered.
The huygens–fresnel principle is a method of analysis applied to problems of wave propagation both in the far-field limit and in near-field diffraction and also reflection. It states that every point on a wavefront is itself the source of spherical wavelets, and the secondary wavelets emanating from different points mutually interfere. Wave refraction in the manner of huygens wave diffraction in the manner of huygens and fresnel.
Huygens principle is also known as the huygens–fresnel principle. This principle was named after dutch physicist christiaan huygens and french physicist augustin-jean fresnel. It is a method of analysis that applies to problems of wave propagation both in the near-field and far-field limit and in near-field diffraction and also in reflection.
Huygen’s principle also sometimes called as huygens–fresnel principle states that each point on a given wavefront is a source of secondary wavelets or secondary disturbances. Further, the disturbances originating from the secondary source spreads in all directions in the same way as originating from the primary source.

The term huygens' principle, however, was not clear until its precise mathemat- icd meaning, within the context of the theory of hyperbolic partial differentid.
Huygens' principle can be seen as a consequence of the homogeneity of space—space is uniform in all locations. Any disturbance created in a sufficiently small region of homogenous space (or in a homogenous medium) propagates from that region in all geodesic directions.
Huygens’ principle embodies a simple but powerful physical concept that serves to explain in a lucid manner how an arbitrary wavefront progresses from one point to another (robinson and clark, 2006b). According to this hypothesis, each individual point on an advancing wavefront is disturbed.

Describe all second-order hyperbolic equations for which huygens' principle holds. From the results of hadamard it follows that huygens' principle can hold only in the case of an odd number of dimensions. For a long time it was thought that all such equations can be reduced to the usual wave equation using the following transformations, called elementary:.
