Askeri Gizleme Uygulamaları İçin Plazma Kaplamaların Tasarımı

Abstract

In this study, propagation of electromagnetic wave in inhomogeneous plasma slab is analyzed for different electron distributions and for normal and oblique incidence cases. Plasma slab is considered in air and also it considered as a cover layer on perfect conductor. In order to get wide absorption band in military stealth applications, proper plasma parameters such as electron density function, collision frequency and plasma thickness, and also external dc magnetic field value are determined. In the study, in addition to some electron density distribution functions in literature, new functions depending on Fibonacci series, Fibonacci numbers and golden ratio are also proposed and applied to plasmas used in coating applications and results are discussed. According to the results, most of the proposed plasma coatings are proposed for wide band stealth applications requiring high absorbtion rate in future.
