Abstract
A uniform asymptotic solution is presented for the diffraction of Ez polarized plane waves by a resistive strip residing between two impedance half-planes. The analysis proceeds from triple integral equations approach which leads to a system of uncoupled modified Wiener-Hopf equations (MWHE). This system is then reduced to two pairs of Fredholm integral equations of the second kind which are solved by successive approximations. Diffracted field expressions are derived up to the third order terms which include the surface wave field effects in a uniform manner.
Résumé
Une solution asymptotique uniforme est obtenue pour la diffraction des ondes planes polarisées Ez par un ruban résistif placé entre deux demi-plans à impédance. L’analyse part d’équations intégrales triples qui conduisent à un système d’équations découplées de Wiener-Hopf modifiées. Ce système est ensuite réduit à deux paires d’équations intégrales de Fredholm de seconde espèce qui sont résolues par approximations successives. Les expressions des champs diffractés sont dérivées jusqu’aux termes du troisième ordre qui incluent les effets de champ d’onde de surface d’une manière uniforme.
