Spatio-Spectral Analysis of Electromagnetic Wave Propagation

Yıl 2019, Cilt: 2 Sayı: 1, 15 - 18, 18.07.2019

Numerical methods such as Finite Difference Time
Domain Method (FDTD) solution of Electromagnetic Waves (EMW) are particularly
useful for transient analysis of EMW propagation. However, transient analysis
methods are not effective for analysis of spectral properties of wave
propagation in anisotropic media. In order to consider frequency dependence of
material parameters (permittivity, permeability and conductivity),
frequency-depended FD-FDTD methods ((FD)2TD) are proposed. Besides,
high computational complexity and stability problems of solution, relevance of
solution is questionable.  There is a
need for straight forward analytical solution for perform spatio-spectral
investigation of basic structures and the verification of simulation results.
This study presents a solution of Maxwell equations for directional wave
propagation in media where dielectric constant expressed with respect to wave
frequency. This provides low complexity fundamental analyses of EMW propagation
in homogeneous material.

Elektromanyetik Dalga Yayılımının Uzaysal-Spektral Analizi

Farklı elektrofiziksel özelliklere sahip lineer, homojen ve izotrop ortamlarda elektromanyetik dalga (EMW) yayılmasının
transient analizi için zamanda sonlu farklar metodu (FDTD) gibi sayısal yöntemler önem arz etmektedir. Bununla birlikte, transient
analiz yöntemleri, anizotropik ortamdaki dalga yayılımının spektral özelliklerinin analizi için pek etkili değildir. Bu nedenle,
elektromanyetik dalganın yayıldığı bir ortamda, ortam parametrelerinin frekansa bağımlılığını (𝜀𝑎-elektrik geçirgenlik, 𝜇𝑎-manyetik
geçirgenlik ve 𝜎-iletkenlik) dikkate almak için, frekans bağımlı FD-FDTD yöntemleri ((FD)2TD) önerilmiştir. Ayrıca, problemin
çözümü esnasında oluşan yüksek işlemsel karmaşıklık ve kararlılık problemleri, çözümden elde edilen sonuçların sorgulanmasını
gerektirmektedir. Temel yapıların uzaysal-spektral incelemesi ve simülasyon sonuçlarının doğrulanması için ileri analitik çözüme
ihtiyaç vardır. Bu çalışmada, dielektrik sabitinin dalga frekansına göre ifade edildiği ortamlarda yönlü dalga yayılımı için Maxwell
denklemlerinden hareketle elde edilen çözüm verilmiştir. Elde edilen sonuçlar, düşük karmaşıklıktaki bir homojen yapıya sahip bir
materyalde EM dalga yayılımının temel analizlerine olanak sağlar.
