Abstract Metasurfaces enable precise manipulation of electromagnetic (EM) waves for applications such as beam steering, sensing, and stealth technology. However, inverse design of metasurfaces remains challenging owing to the computational burden of iterative full-wave simulation-driven optimization, the difficulty of achieving controllable generation under continuous EM constraints, and the inherently non-unique nature of the inverse mapping.

Global dairy markets have entered 2026 with supply conditions still firmly in control, according to the latest Global Dairy Quarterly from Rabobank. The report notes that milk production across the major exporting regions remains elevated. However, growth momentum is expected to slow sharply over the course of the year. Output from the so-called “Big 7” dairy exporters is forecast to expand by just 0.2 per cent year-on-year, signalling a near-flat growth environment after previous expansion cycles.

The Goa Government has launched what is being positioned as the world’s largest Dynamic QR-based Deposit Return Scheme (DRS), covering more than two billion packaging units annually. Scheduled to become operational this April, the initiative represents a significant shift in India’s approach to packaging waste management, traceability, and extended producer responsibility (EPR).
