Upon conclusion it was found that dispersion relation for the waves is differ significantly from that of cold plasmas and the dispersion increases with increase of the warmness of dusty plasma (ω2 /kz2)α(Vtd2). The permittivity and instability of dusty plasma was calculated and it was clear that it is more affected by the warmness of dusty plasma while the permittivity ε=[1-(ωpd2/Htdω2)] decreases by increase of the warmness of dusty plasma, Htd=1-(3kz2Vtd2/ω2).  ISSN : 1313-1311  Journal Name : Advanced Studies in Theoretical Physics  Volume : 5  Issue Number : 9  Publishing Year : 1432 AH 2011 AD  Article Type : Article  Added Date : Wednesday, April 25, 2012  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email N M El Siragy El Siragy, N M Researcher Doctorate   A A El-Bendary El-Bendary, A A Researcher Doctorate abendary15@hotmail.com خالد حامد الشوربجي El-Shorbagy, Khaled Hamed Researcher Doctorate shorbagy4@Hotmail.com B M Dakhel Dakhel, B M Researcher Doctorate drkhalede@yahoo.com Files File Name Type Description  33033.pdf pdf Abstract Back To Researches Page
