Abstract :
The electromagnetic field is expressed both in terms of circular and elliptical cylindrical wave functions, which are connected with one another by well-known expansion formulas. In the special case of small h=ka/2 (a is the interfocal distance of the elliptic conductor and k the wavenumber of the dielectric coating), exact closed-form expressions of the form S(h)=S(0) [1+g"h2+0 (h4)] are obtained for the scattered field and the various scattering cross-sections of the problem
