Dynamically Tunable Electromagnetically Induced Transparency in a Vanadium-Dioxide-Based Terahertz Metasurface

This paper proposes and numerically investigates a dynamically tunable terahertz metasurface integrated with vanadium dioxide that achieves reversible switching between an electromagnetically induced transparency state with slow-light characteristics and a broad transmission band by exploiting the material's insulator-to-metal transition to modulate mode coupling and ohmic losses.

Bifilm generation in metal handling and degassing: Total numbers, sizes and damage

This study reveals that conventional testing significantly underestimates oxide bifilm populations in cast aluminium alloys, demonstrating through theoretical modeling and advanced 3D reconstruction that melt transfer is the primary source of these defects and that current rotary degassing practices may inadvertently increase damage at specific rotation rates.

A Spectral Coherence Framework for Light: The Lunet Hypothesis and Its Implications for Wave-Particle Duality

This paper proposes the "Lunet Hypothesis," a theoretical framework grounded in the non-trivial zeros of the Riemann zeta function, which resolves wave-particle duality by positing that light's manifestation as a wave or particle depends on its degree of spectral coherence.
