मेटासामग्रियां संवेदन, इमेजिंग और संचार में उन्नत अनुप्रयोगों के लिए अद्वितीय गुणों वाली कृत्रिम संरचनाओं के अभिनव इंजीनियरिंग को सक्षम बनाती हैं।

मेटासामग्रियां कृत्रिम रूप से इंजीनियर की गई संरचनाओं से बनी होती हैं जो विद्युत चुम्बकीय, ध्वनिक, or mechanical properties unattainable in natural materials, achieved through subwavelength patterning and tailored unit cell design. This domain explores negative refractive indices, cloaking, superlensing, tunable responses, and anisotropic behavior across microwave, terahertz, optical, and acoustic regimes. Advances in metasurfaces, plasmonics, chiral configurations, and nonlinear effects enable unprecedented control over wave propagation, polarization, and dispersion. Our continuously updated compilation hereafter presents the latest peer-reviewed research and patented technologies addressing fabrication techniques, theoretical modeling, device integration, and application-specific innovations critical for next-generation sensing, imaging, संचार, and stealth technologies:

Abstract: Polymer Journal, Published online: 16 October 2026; doi:10.1038/s41428-026-01262-6A simple method for expanding the Bragg reflection width of elastomer-immobilized, nonclose-packed colloidal photonic crystal films using a mixture of two types of elastomer precursors was proposed. For the elastomer-immobilized, nonclose-packed colloidal photonic crystal film exclusively prepared using 4-hydroxybutyl acrylate (4HBA), the full width at half maximum of the Bragg reflection peak was 19 nm; this val[...]


Our summary: A method for expanding the Bragg reflection width in elastomer-immobilized colloidal photonic crystals was developed using a binary mixture of elastomer precursors. The addition of 2-hydroxyethyl methacrylate significantly increased the Bragg reflection peak width from 19 nm to 186 nm. This technique aims to enhance the use of these crystals in structural color applications and optical filtering.
