Abstract
The transmission coefficient of a radiating horn is calculated. The calculation imposes a radiation condition at large distances. It employs the boundary integral method developed by Bernstein and Rokhlin. It is performed in the frequency domain and assumes axial symmetry. We discuss the dependence of rf transmission for the horn geometry that is used in the relativistic klystron amplifier experiments at the Naval Research Laboratory.
