Patterned Ground Shields For Silicon RFICs Part 2: What Universe Are We In?

2013-05-29 12:56:26| rfglobalnet News Articles

In Part I, we used Sonnet® to investigate the current in the surface of the silicon substrate that is induced by a spiral inductor. Since it is an inductor, we were expecting the substrate current to be induced magnetically. After all, inductors are just little magnets, and we would expect inductively induced current in any nearby conductor. The silicon substrate is a conductor, kind of, right? In addition, the magnetically induced current should flow parallel to (and in the opposite direction of) the current in the spiral inductor. This behavior obeys a special case of Clerk Maxwell’s equations known as Lenz’s Law. This is all, to use American slang, a “slam-dunk”1, hardly even worth checking.

US crop insurance shields farmers from drought

2013-05-02 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Bloomberg: When dry weather destroyed Leonard McKissick's soybeans last year, US government-backed insurance paid him $US40,000, the bulk of his loss. Across the Arkansas Delta this spring, farmers such as McKissick are sowing fields that suffered the worst drought in more than half a century. Even though crops may fail again, landowners are shielded by taxpayers from the full burden of their bad bets. Drought helped drive the cost of crop insurance to a record $US17.2 billion, the US Department of Agriculture...
