RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer.

The Global Brain Trade

The Global Brain Trade - RF CafeThe September 2012 edition of IEEE's Spectrum magazine has an interesting chart on the last page that shows the percentage of researchers that immigrate/emigrate to/from 16 different countries versus how many emigrate from the them. The chart bars represent percentages, not absolute numbers. Switzerland has the highest number of researchers immigrating to it (~60%) while about 35% emigrate from it. We don't know whether any of those immigrants stayed a while and then joined the emigrants ranks. India has the greatest number of researcher emigrants leaving (~40%) while immigrants relocating to India are almost immeasurable. China is not included because access to researchers there was too restricted (gotta love those Communist regimes).
