Abstract

Requirements for waveguides of millimeter waves are demanding. Ongoing works have been conducted seeking waveguides with better characteristics. Many consider groove guides to be promising waveguides for short millimeter waves based on their easy manufacture and small influences due to bendings. However, earlier works on groove guides have focused on rectangular grooves. Their analyses were approximate and there were no rigorous analyses. This paper rigorously analyzed three types of groove guides via the method of boundary elements. We obtained the electromagnetic fields of the transmitted modes and various transmission properties such as cutoff frequencies, dispersion characteristics and attenuation characteristics. As a result, we clarified that groove waveguides had low losses and low dispersion. In practice, it may be possible to realize their uses for short millimeter waves.
