THE PROPAGATION OF CURRENT ALONG INFINITE SINUSOIDAL TAPES

摘要

This work is a study of the propagation and radiation characteristics of electric current on infinite sinusoidal conducting tapes. The determinantal equation for the propagation constant, βo, is derived for both planar and ribbon tapes. With the aid of a digital computer the determinantal equation for the planar tape is solved and the results are plotted in the form of Brillouin or dispersion diagrams. The results of measurements on experimental models are presented and compared with the theoretical predictions.nThe approach, used in this work to investigate the propagation characteristics of sinusoidal tapes is based on Floquet's theorem and a Fourier expansion of the space variation of the electric current on the tape structure.
