Abstract: In this paper, a 3D-printed dual-band reflect-transmit-array (RTA) antenna has been presented, which operates as a reflectarray (RA) in the 28 GHz band and as a transmitarray (TA) in the ...

Once the stuff of science fiction, 3D printers are now mainstream tools for creation and innovation. These devices, which transform digital blueprints into physical objects, have dramatically evolved ...

The rise of the consumer 3D printer has yielded amazing devices for designers, engineers, hobbyists, tinkerers, and schools alike. I've been reviewing 3D printers for PCMag since the first widely ...

More affordable than ever, 3D printers are booming for personal, professional, and educational use. We've been testing them for over a decade and are here to help you find the right option. Since 2004 ...

Today's affordable 3D printers will surprise you: You can get a smooth-working machine with useful features once reserved for high-end models. Starting at just $250, these are the top budget ...

Abstract: In the development of a complementary metal-oxide-semiconductor (CMOS) under array (CuA) structured 3D NAND memory, the through-array contact (TAC) process plays a critical and indispensable ...
