Shape-shifting antennae adapt in real time to cloak and block frequencies

Radio frequency filters can change which signals they block through a range of frequencies, using an origami-based structure to change their dimensions. Researchers at the Georgia Institute of Technology say that the tunable filters can be used in antenna systems that adapt to ambient conditions in real-time for electromagnetic cloaking systems that could be reconfigured on-the-fly to reflect or ...

Conductive ink breakthrough reduces cost of graphene printed electronics

Researchers at the University of Manchester have identified dihydrolevogucosenone, a non toxic material which is less expensive than conventional conductive inks. It is a sustainable material that provides higher concentrations and conductivity compared with graphene ink and is lower in cost as it does not rely on metal nanoparticles for electrical conductivity in printed electronics. Printed conductive inks are being ...

Fab investment goes into reverse

Fab equipment spending in 2019 is projected to drop 8%, down from the previously forecast increase of  7%, says SEMI. Total fab investment growth has been revised downward for 2018 to 10% from the 14% predicted in August. Entering 2018, the semiconductor industry was expected to show a rare fourth consecutive year of equipment investment ...

Intel makes early moves for more fab

Suffering from a shortage of capacity for CPUs, Intel is now moving early to ensure that it will have futire capacity when it needs it. The company says it has begun talks with the planning authorities in Israel, Ireland and Oregon about extending capacity  at those sites. The inetention is that construction could begin at ...
