The scattering properties of a dielectric-coated nonconfocal conducting elliptic cylinder are investigated. The theoretical treatment of such a problem is based on the boundary value solution, which is an exact treatment of the problem. Only the transverse magnetic (TM) case is considered here, while the transverse electric (TE) case can be treated in the same way. It is shown that this solution is much more general than all other solutions given before because it can handle a variety of scattering geometries. Numerical results are presented in graphical form for the echo width pattern of various geometries.

The scattering cross section of a dielectric elliptic cylinder coated with nonconfocal dielectric is investigated. An exact dual series solution based on the boundary value method and employing the addition theorem of Mathieu functions is derived. Both transverse magnetic and transverse electric cases are considered. The infinite series' of the solution are truncated after a finite number of terms to generate numerical data. A convergence check is built into the computer program, and the geometrical dimensions considered are within the low‐frequency range. It is shown that this solution is much more general than all other solutions given before because it can handle a variety of scattering geometries.
