Abstract
An ultrasonic waveguide for guiding an ultrasonic signal situated in a predetermined frequency range is illustrated and described. The ultrasonic waveguide according to the invention is characterized in that it has a coiled foil whose layer thickness is considerably less than the smallest wavelength of the ultrasonic signal in the predetermined frequency range in the foil material. The result is that ultrasonic signal interference and attenuation in the ultrasonic waveguide due to scattering and dispersion are largely avoided.
