TY - JOUR TT - Yutucu Yarım Düzlemin Kenarından Kırınan Üniform Alanların Fiziksel Optik Yöntemiyle Hesabı AU - Sarnık, Mücahit AU - Yalçın, Uğur PY - 2010 DA - April JF - Cankaya University Journal of Science and Engineering JO - CUJSE PB - Cankaya University WT - DergiPark SN - 2564-7954 VL - 7 IS - 2 KW - Physical optics KW - Green’s theorem KW - diffracted field KW - detour parameter N2 - In this study, the uniform scattered fields from a black half plane are calculatedwith the physical optics method. The expression, which is found by physical opticsmethod, is written in terms of Fresnel function by using detour parameter and the uniformsolution is found. Hence a finite solution is obtained for all the values of observation angle.Moreover, the found results are compared numerically with the exact solution. CR - [1] F.
