The material presented in the report is intended to furnish a unified approach to understanding 1 the physical behavior of multiwire transmission lines as used in the realization of high-frequency electrical filters and couplers, and 2 the response of open-wire lines and of shielded cables to end excitation or to continuous excitation along the line by external electromagnetic fields. Scope of development is restricted entirely to monochromatic behavior of linear time-invariant systems, since, from that base, the response of the line to transient applied forces is readily synthesized by means of the Fourier theorem. The theory of lossless lines in homogeneous, isotropic dielectrics is applied in the derivation of basic line parameters of simple transmission line models. These parameters are related to the classical Maxwell capacitance coefficients. A number of practical configurations are discussed on which the designs of directional couplers, inductive and capacitive couplers, and wave filters, are based.
