Abstract

In the present study,
reflected and diffracted fields of an inhomogeneous plane wave obliquely
incident on the surface of a perfectly electric conducting (PEC) half plane are
evaluated for a two-dimensional case asymptotically and reexamined by
considering the different aspects. Obtained results are plotted by Matlab
numerically. Relationships between the complex angle of incidence and field
intensities, and phase shifts in the fields are noted. Matlab plots are
interpreted and compared to the theory for consistence.

Abstract

Bu çalışmada mükemmel elektrik iletken (MEİ) yarım
düzlemine eğik olarak gelen homojen olmayan (inhomojen) bir düzlem dalganın
yansıyan ve kırınan alanları iki boyutlu durum için asimptotik olarak
hesaplanmış ve farklı yönlerden yeniden incelenmiştir. Elde edilen sonuçlar
Matlab ile sayısal olarak çizdirilmiştir. Kompleks geliş açısıyla alan
yoğunlukları ve alanlardaki faz kaymaları belirlenmiştir. Matlab çizimleri
yorumlanmış ve uyumluluk için teoriyle karşılaştırılmıştır.
