![]() During his 35-year career at Bell Labs, Schelkunoff's research included, propagation in the atmosphere and in microwave guides, broad-band, and grounding. In 1935 he and his colleagues reported that, then new, could transmit pictures or up to 200 conversations. Schelkunoff appears to have been the first to notice the important practical consequences of the fact that attenuation in the decays inversely with the 3/2 power of the frequency. Mead began analysis of propagation discovered analytically by their colleague. Teaching, the IEEE APS Distinguished Career Award (1992), the IEEE Schelkunoff Prize Paper Award. ![]() Professor Collin was a life fellow of the IEEE, fellow of the Electromagnetic Academy, and member of the Microwave Theory and. After receiving his degree, Schelkunoff joined 's research wing, which became.ĮLECTROMAGNETIC WAVES. From for his dissertation On Certain Properties of the Metrical and Generalized Metrical Groups in Linear Spaces of n Dimension. There he received bachelor's and master's degrees in mathematics from the State College of Washington, now the, and in 1928 received his Ph.D. ![]() He crossed into and then before settling into in 1921.
