دراسة حول تأثير الحركة الحرارية لإلكترونات البلازما المتجانسة والمتماثلة المناحي على سماحية عازليتها الكهربائية
Abstract
يهدف البحث الراهن إلى تعيين سماحية العازلية الكهربائية للبلازما المتجانسة والمتماثلة المناحي عند أخذ الحركة الحرارية لإلكتروناتها بعين الاعتبار.
فبعد استخراج سماحية العازلية وتعيين علاقة التبدد، تمّ برهان فقدان البلازما حالة الاعتدال الكهربائي من جراء تأثير الاضطراب المطبق بفعل موجة كهرطيسية مستوية غير كبيرة السعة، ودراسة تغير الكثافة الحجمية للشحنة المتشكلة بتغير الزمن، والتأكد من صحة هذه الدراسة من خلال تحقق قانون انحفاظ الطاقة الكلية.
The aim of the present work, is to determine the dielectric permittivity of homogenous and isotropic plasma, where its thermal motion electrons is taken into consideration.
After obtaining the dielectric permittivity and the dispersion relation, we proved the existance of plasma – loss to the electric neutrality, by applying a disturbance (of not – so – wide amplitude) of an external-plane electromagnetic wave. Also we have studied the volume density variation of the formed charge-via-time, confirming this study from the verification of the total energy conservation law.
