ABSTRACT:
An electric wave operating device for efficiently coupling electromagnetic energy from a waveguide into a dielectric element or vice versa. A waveguide horn portion is chosen for radiating in the primary HE.sub.11 mode and designed to have a predetermined HE.sub.11 mode farfield radiation pattern. A dielectric member is securely disposed with one end in the plane of the aperture of the waveguide horn with the dielectric member having a predetermined HE.sub.11 mode farfield radiation pattern substantially equal to the farfield radiation pattern of the horn.
