(That is, light does not always propagate on the light cone). This inside-the-null-cone propagation of waves is known as the tail effect, and finding novel ways of understanding it in the strong field regime near a black hole may find applications for modeling the gravitational signals sought after by next-generation space-based detectors such as LISA.

Such operators are a rough model for the propagation of waves inside a disordered medium.

The second contributor is the propagation of waves in the contact and messenger wires.
Extensive efforts have previously been exerted to investigate the propagation of waves in two-dimensional periodic structures.
The propagation of waves in case of non-heat conducting solids is also discussed.
The propagation of waves through homogeneous or layered soil is calculated based on half-space theory.
The equations describing the propagation of waves (electromagnetic, acoustic, deep water waves, and ripples) are discussed in relevant articles, as is the Schrödinger equation for probability waves that governs particle behaviour in quantum mechanics (see below Fundamental constituents of matter).
Propagation of waves in the very-high-frequency range and above, which penetrate the ionosphere, can be affected by temperature changes in the stratosphere, that part of the atmosphere up to about 15 kilometres (nine miles) from the Earth's surface.
