A novel design to reduce losses at dielectric waveguide discontinuities

A novel approach to reduce losses of dielectric waveguide bends and junctions is examined in this paper. Ceramic material is added at the bend or the junction. The ceramic's dielectric constant, its shape and size, and position relative to the bend, are several parameters that can be varied to minimize the losses at the junction. Finite-difference time-domain analysis of a representative case is presented.<
