Abstract :
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.<>
