It started as a simple idea. Now it’s a massive, barely-movable sphere of rubber bands. I added more weight, more layers, and pushed it closer to the limit. The real question is… how big is too big?

Abstract: In this contribution, the design and manufacturing of an all-metal coaxial-line X-band bandpass filter is discussed. The device is 3D-printed as a self-supported structure without any ...

The strength and texture of rubber bands mean they can come in handy around the house in ways you might not have realized.

Abstract: This paper presents a novel structure for designing a dual-band (DB) rectifier with high efficiency and compact size for wireless power transfer. The proposed circuit employs a simple dual ...
