Discover an amazing technique that few people know about—sharpening drill bits to restore their functionality and precision.

In this comprehensive guide, learn how to sharpen drill bits effectively using an angle grinder. Perfect for both DIY ...

In this work, an angle-insensitive 3-bit RIS meta-atom is proposed. By introducing metallic vias in the substrate of programmable meta-atoms, the interference induced by multiple reflections in the ...

In this paper, a 1-bit reconfigurable reflectarray antenna (RRA) based on a programmable metasurface is presented. The capability for angular insensitivity is achieved through a unit-specific wing ...
