PLANE-WAVE SCATTERING BY DIELECTRIC ELLIPTIC CYLINDER COATED WITH NONCONFOCAL DIELECTRIC

The scattering cross section of a dielectric elliptic cylinder coated with nonconfocal dielectric is investigated. An exact dual series solu tion based on the boundary value method and employing the addition the orem of Mathieu functions is derived. Both transverse magnetic and tra nsverse electric cases are considered. The infinite series' of the sol ution are truncated after a finite number of terms to generate numeric al data. A convergence check is built into the computer program, and t he geometrical dimensions considered are within the low-frequency rang e. It is shown that this solution is much more general than all other solutions given before because it can handle a variety of scattering g eometries.
