Abstract : An electric wave operating device for efficiently coupling electromagnetic energy from a waveguide into a dielectric element or vice versa. A guide horn portion is chosen for radiating in the primary HE11 mode and designed to have a predetermined HE11 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 HE11 mode farfield radiation pattern substantially equal to the farfield radiation pattern of the horn. PAT-CL-343-785. (JES)
