Bu çalısmada Green fonksiyonu formülasyonu ve Moment yöntemi kullanılarak, rezonans bölgesinde ve “yüksek kırıcılık yaklasıklıgı” (YKY) altında, düzlemsel sınıra sahip kayıplı dielektrik yarı-uzay üzerinde konuslanmıs metalik ince tel ızgara yapılarına iliskin saçılma problemleri incelenmistir. Bu amaçla Moment yöntemindeki empedans matrisinin hesabında, literatürde ilk defa olarak, R.W.P.King'in YKY altında her uzaklık için geçerli Green fonksiyonları kullanılmıstır. Gelistirilen MATLAB™ tabanlı yazılımı dogrulama amaçlı olarak düzlem dalga uyarımı altında belirli kanonik yapılar üzerinde elde edilen akım dagılımlarının sayısal degerleri SNEC™ ticari yazılımı ile elde edilen degerlerle karsılastırılmıstır.
