Extinction Cross Section of a Dielectric Strip

The problem of scattering of a plane electromagnetic wave by a dielectric strip is formulated in terms of an uncoupled system of three-part Wiener-Hopf equations by using a set of approximate boundary conditions. The resulting Wiener-Hopf problems are solved approximately for sufficiently large values of the width of the strip by using D.S. Jones' method (1964). An analytical formula is derived for the excitation cross section of the strip under consideration from which numerical values are obtained in specific situations and the results are presented graphically. The radar cross section of the strip is also computed for several special circumstances, and these are presented separately
