abstract = "This paper presents the propagation characteristics in straight open-groove structures in UHF based on the imperfect waveguide method. The attenuation constant due to surrounding media absorption, sidewalls tilt and the roughness of the sidewalls are considered and corrected. Numerical results are presented for the attenuation constant. These results show that the losses due to the roughness of the sidewalls are inversely proportional to the frequency and losses due to sidewalls tilt is the main cause of power loss at high frequencies. Thus attenuation due to absorption and roughness of the sidewalls are negligible in comparison to attenuation due to sidewalls tilt in this frequency range.",
