Special Issue Information
Dear Colleagues,
The rapid advancement of micro- and nano-structured materials has brought non-Fourier (finite-speed) heat transport to the forefront of thermal science. Traditional Fourier-based models fail to capture transient, wave-like heat propagation observed in phonon hydrodynamics, hyperbolic heat conduction, and nanoscale devices. This Special Issue, “Non-Fourier Thermal Wave Crystals: Fundamentals, Modeling, and Applications,” invites original contributions that advance understanding of how periodic or quasi-periodic architectures—such as layered composites, phononic/metamaterial lattices, and patterned crystals—influence non-Fourier thermal waves. We welcome research that (i) develops or applies rigorous models of non-Fourier heat transport (e.g., Cattaneo–Vernotte, phason/phonon hydrodynamics, and dual-phase lattice approaches) in periodic media, (ii) analyzes dispersion, band gaps, anisotropy, and attenuation of thermal waves, and (iii) demonstrates practical applications in thermal management, thermoelectrics, cloaking, and energy harvesting. Submissions may span theory, computational methods (e.g., Bloch/Floquet analysis, multiscale simulations), and experimental developments, including micro-/nano-scale measurements and device-level prototypes. By connecting fundamental wave physics with engineered crystal geometries, this Special Issue will chart design principles for controlling heat with wave-like fidelity and to inspire innovative thermal management solutions in electronics, energy, and materials science.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Crystals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
