Diffusion-wave Fields: Mathematical Methods And... Apr 2026

Key mathematical tools used to analyze these fields include:

The mathematical nature of these fields is primarily defined by the when subjected to periodic (harmonic) excitation. While standard waves (like sound or light) propagate with distinct wavefronts, diffusion waves are highly damped and "lack wavefronts," meaning they do not travel far and cannot be easily beamed. Diffusion-Wave Fields: Mathematical Methods and...

Diffusion-wave fields refer to a specialized category of periodic phenomena where diffusion-related processes behave mathematically like waves. This concept, extensively developed by Andreas Mandelis in his work Diffusion-Wave Fields: Mathematical Methods and Green Functions , unifies diverse fields like heat transfer, charge-carrier transport in semiconductors, and light scattering in turbid media under a single mathematical framework. Core Mathematical Framework Key mathematical tools used to analyze these fields

: Fourier and Laplace transformations are fundamental for converting time-domain diffusion equations into the frequency domain. This concept, extensively developed by Andreas Mandelis in

: Used to solve boundary-value problems across various geometries (Cartesian, cylindrical, spherical) for both infinite and finite domains.
