Investigation of Polarization Dependent Interaction of Microwave and Plasma by Using Fluorescent Lamp Array

Abstract

In this study, polarization-dependent microwave interaction with a fluorescent lamp array was investigated. This interaction was examined with a receiver and transmitter at 10.5 GHz frequency. The fluorescent lamp array was driven by 220V/50 Hz mains. Measured microwave signal change was around 77.5% in the energized state and 8.7% in the non-energized state of the lamp array due to polarization. It has been shown that if an array is used as a polarizer in this way, a polarizer with an extinction ratio of 6.35 dB can be obtained.

Kutuplanmaya Bağlı Mikrodalga Plazma Etkileşiminin Floresan Lamba Dizisi ile İncelenmesi

Abstract

Yapılan bu çalışmada, floresan lamba dizisi ile kutuplanmaya bağlı mikrodalga etkileşimi incelenmiştir. Bu etkileşim, 10,5 GHz frekansında alıcı ve verici kullanılarak araştırılmıştır. Floresan lamba dizisi 220V/50 Hz şehir şebekesi kullanılarak sürülmüştür. Alıcıya ulaşan mikrodalga sinyalinde, lamba dizisinin enerjili durumda %77,5 ve enerjisiz durumunda ise %8,7 kutuplanmaya bağlı değişim gözlenmiştir. Tasarlanan floresan dizisinin kutuplayıcı olarak kullanılması durumunda yok etme oranı 6,35 dB olan bir kutuplayıcı elde edilebileceği gösterilmiştir.
