Abstract
A flexible waveguide has a flexible wall enclosing an elongated cylindrical passage for transmission of an electromagnetic wave along the passage. A succession of corrugations is disposed along an interior surface of the wall facing the passage. The corrugations are spaced apart by a distance less than approximately 0.2 wavelength of the electromagnetic wave, each of the corrugations having a height greater than the distance but less than approximately 0.5 wavelength of the electromagnetic wave, and each corrugation having a curved surface to minimize loss in the transmission of the electromagnetic wave.
