Coping with a Rapidly-Growing 'Knowledge Gap'

Advancing technology always creates changes in the knowledge required by its practitioners. In radio engineering, an obvious series of changes was from spark to vacuum tubes, to transistors, to ICs—along with accompanying advances in materials and processes. Microwave specialists moved up in fre-quency and down in size, and are constantly adding a whole host of devices, materials and applications. Digital engineering didn’t even exist until the 1940s, and has undergone an evolution of historic proportions—with operating speeds that are beyond what was considered “microwaves” 50 years ago. Optical communications, once considered to be completely different, is now part of the overall communications technology package and is moving to chip-level implementation.
