15. To the best of our knowledge, even for a metallic millimeter-wave 90° waveguide bend, the best commercially available one has a bending radii of 4 to 5 wavelengths.
16. Our measurement is accurate to about ± 5% mainly because of an amplitude oscillation caused by resonance between the input and output end of the PBG guide. Also, the absolute bending efficiency is slightly lower, ∼3%, because the <10> and <01> sections of the bend would contribute to a small guiding loss.
