    摘要: A flexible waveguide for the correct transmission of electromagnetic waves, comprising a relatively thin, seamless metal waveguide tube having a noncircular internal cross section, the edges or profile which is free of abrupt changes of direction. Means are provided, according to the invention, for imparting a rigidity to the waveguide tube which will reduce to a minimum any deformation of the internal cross section, when the waveguide is bent or twisted.

    摘要: A flexible waveguide has an elongated hollow body having a noncircular cross section in which the ratio of the width of the wide side to the narrow side is less than 0.5. The body cross section includes an indentation extending along the longitudinal axis of the wave guide. The indentation is so shaped and the ratio of the width of the wave guide at the indented point to the width of the narrowest side is so small that interfering wave types do no occur.
