For certain applications of beam waveguides to large ground system antennas, the use of ellipsoid pairs in place of more conventional paraboloid pairs is appropriate. For example, in the application illustrated in Figure 1, the feed and maser system is rotated in azimuth with the antenna. In this case, the beam waveguide does not go directly to the axis of the main reflector but bypasses some in-place heavy machinery along this axis. In this configuration, ellipsoid pairs are more suitable because their convergent ray characteristic allows for a lower loss transmission and also because the three independent focii can be aligned in accordance with the rules discovered by Mizusawa and Kitsuregawa.l Thus aligned, the ellipsoid pair perfectly images the feed pattern according to geometrical optics (see Figure 2).

In this paper the scattered field due to a plane wave incident on two parallel multilayered dielectric cylinders is derived using the boundary value approach. An asymptotic solution is also presented in which fictitious line sources located at the cylinder axes are used to account for the multiple interactions. For the sake of simplicity two layered-dielectric cylinders and two dielectridy coated conducting cylinders are investigated, however the solution can be easily extended to many layers as well as to many cylinders.
