Abstract

Designs are described for flexible hollow waveguides with low ir loss over distances on the order of 1 m. Transmission losses at 10.6 μm are calculated, and the effect of bends and twists is discussed. A hollow combination metal-dielectric-walled rectangular waveguide is proposed that can have transmission as high as 95% for a 1-m length, while bent with a 1-m radius of curvature.
