Abstract :
A novel waveguide directional coupler configuration consisting of a slab of anisotropic material with identical waveguides on both surfaces is proposed. By off-axis propagation the radiative part of a leaky wave provides a coupling between waveguides. The length of total power transfer depends on the slab´s thickness and propagation angle relative to the optic axis.
