Up until now, the invisibility cloaks put forward by scientists have been fairly bulky contraptions – an obvious flaw for those interested in Harry Potter-style applications. However, researchers from the U.S. have now developed a cloak that is just micrometres thick and can hide three-dimensional objects from microwaves in their natural environment, in all directions and from all of the observers’ positions.
Vishay Precision Group Inc. announced that the company has opened a new Vishay Foil Resistors (VFR) Precision Center within Digi-Key Corp., a global full-service provider of both prototype/design and production-quality electronic components. Digi-Key can now build and ship VFR surface-mount precision resistors — with no minimum quantities — in 24 to 48 hours, including VFR's popular new Bulk Metal® Foil VSMP (Z-Foil Technology) and VSM series resistors.
