NRW Metodu İle Malzemelerin Elektromanyetik Parametrelerinin Bulunması

Year 2018, Volume: 1 Issue: 1, 13 - 19, 08.08.2018

Abstract

NRW algoritması, malzeme karakterizasyonunda
kullanılan yansıma ve geçiş ölçüm tekniğinin hesaplama yöntemlerinden
birisidir. Bu çalışmada, NRW algoritması MATLAB programında yazılan bir kod ile
oluşturulmuştur ve bu program CST benzetim sonuçlarından elde edilen saçılma parametrelerini
girdi olarak kullanmaktadır. Benzetimlerde dikkat edilecek en önemli nokta
referans düzlemi tanımlanmasıdır. Bu düzlem malzemelerin iki yüzeyi olacak
şekilde seçilir. Referans düzlemi tanımlanmadan yapılan benzetimlerin,
literatürde bilinen değerlerden oldukça farklı sonuçlar verdiği
gözlemlenmiştir. Referans düzlemi seçilerek yapılan benzetimlerde, seçilen
dielektrik ve manyetik malzemelerin R, X ve Ku frekans bantlarında CST
benzetimleri yapılmış ve elde edilen sonuçlar MATLAB kodunda girdi olarak
kullanılmıştır. Elde edilen
έr (dielektrik sabiti)
ve
 
έr (kayıp terimi)
değerleri literatürde bilinen değerleriyle karşılaştırılmıştır
