CPW 发明人 Chen P.Wen

stupid

偶然翻书，发现广为使用的CPW 传输线居然是一个华人发明的，呵呵。

" @: r" |1 l, l3 { Cheng P. Wen is the inventor of coplanar waveguide. Working at RCA's Sarnoff Laboratories in Princeton NJ, his 1969 IEEE paper titled "Coplanar waveguide: a suRFace strip transmission line suitable for nonreciprocal gyromagnetic device applications" is proof enough to us that the concept belongs to him alone. After publishing this paper he continued to develop all the bits and piece for CPW circuits, such as lumped element inductors and bumped flip-chip interfaces. One thing we've always wanted to ask Dr. Wen... did he make up the name "coplanar waveguide" so that the acronym CPW is the same as his initials?

Dr. Cheng P. Wen is a visiting Professor at Peking University, Honorary professor of CAS Microelectronics Institute, part time at UCLA, and Global Communication Semiconductors, Inc. Department Manager/Chief Scientist at Hughes Aircraft Company from 1982, retired in 1998. Formerly with Rockwell International Inc. and RCA Laboratories. Inventor of the coplanar waveguide (CPW), and pioneer the development of high power flip-chip MMIC. Research topics covering areas from ultra-low-noise traveling-wave amplifier, gas laser color switching, surface acoustic wave device, magnetic semiconductor, IMPATT devices, long wavelength infrared detectors, short-range automotive radar, to hybrid and monolithic microwave integrated circuits, InGaP/GaAs HBT, GaN HFET and optoelectronics devices.

为啥华人要到他国去，才会...，是否是教育的悲哀呢
