Joseph F. White has studied, worked, and taught in all aspects of microwave semiconductor materials, control diodes, and circuit applications. He is thoroughly grounded in the physics and math- ematics of the field, but has primarily the engineer's viewpoint, combining basic knowledge with experience and ingenuity to gen- erate practical designs under constraints of required performance and costs of development and production. As a result of his teach- ing experience and numerous technical papers and oral presenta- tions, he has developed a clear, well-organized writing style that makes this...
