Recreating the Big Bang with Metamaterials

 

Igor Smolyaninov at the University of Maryland has found a mathematical analogy between optical metamaterials and general relativity. Smolyaninov is researching a way to create metamaterials that reproduce the behavior of light in various kinds of spacetimes. He gives the example of a metamaterial which is a formal equivalent to a (2+2) spacetime with two dimensions of space … [Read more...]

IEC Releases Semiconductor Standard

 

IEC 60749-40:2011 is intended to evaluate and compare drop performance of a surface mount semiconductor device for handheld electronic product applications in an accelerated test environment, where excessive flexure of a circuit board causes product failure. The purpose is to standardize test methodology to provide a reproducible assessment of the drop test performance of a … [Read more...]
