Transmission and coupling losses in a folded waveguide.
This paper discusses the transmission and coupling losses of hollow dielectric waveguide modes in a folded waveguide structure. The folded structure consists of two square-bore waveguides placed symmetrically above a spherical mirror with a nonzero on-axis angle between them. The presence of the fold renders the structure astigmatic. However, for moderate fold angles (10-20 degrees ), the effect of the fold is negligible.
