Analytically Co‐Designed Absorption‐Diffusion Coding Metasurface for RCS Reduction
Microwave and Optical Technology Letters, Volume 68, Issue 10, October 2026.ABSTRACT This work proposes a novel and simple design method for an absorption‐diffusion metasurface, combining a coding diffusion‐type metasurface with an absorbing layer. The diffusion and absorption properties are obtained through an analytical co‐design methodology derived from a straightforward Smith chart‐based construction.

A New High‐Pressure Polymorph of MgTe2O5 with a Unique Crystal Structure
European Journal of Inorganic Chemistry, Volume 29, Issue 26, 16 September 2026.MgTe2O5 synthesized under special high‐pressure/high‐temperature conditions of 8 GPa and 800 °C exhibits a unique crystal structure consisting of fused sechser rings built from pseudooctahedral [TeO5]6– and trigonal‐pyramidal [TeO3]2– units. The single‐crystal structure and temperature‐dependent powder diffraction data are presented.
