SCHELKUNOFF, S. A.

Conversion of Maxwell's Equations into Generalized Telegraphist's Equations.

(New York), American Telephone and Telegraph Company, 1955. 8vo. Original printed blue wrappers. In "The Bell System Technical Journal.", Volume XXXIV, September, 1955, No. 5. pp. 995-1044. [Entire volume: pp. 883-1114]. A bit of sunning to spine. Previous owner's name to front front wrapper. Internally fine and clean.

First edition of Schelkunoff's classic paper on how Maxwell's field equations together with appropriate boundary conditions may be converted into equations analogous to those for coupled transmission lines, making it possible to use well known techniques of dealing with transmission lines to solve certain field problems; applicability to studying waveguide-to-horn junctions, bending of waveguides and propagation of waves.
