Goal of this study is to present an novel time domain approach for the analysis of waveforms which can be excited by a pulse signal in a rectangular cavity filled with a plasma and bounded by perfect electric conductor surfaces. Maxwell’s equations with time-derivative supplemented with initial conditions have been solved under the principle of causality. Dynamic version of the Ohm’s law for plasma was involved in the system of Maxwell’s equations as the constitutive relation between the plasma current vector and the electric field. Solutions for the electric field, magnetic field, and the plasma current have been obtained explicitly in the form of convolution integrals

PLAZMA İLE DOLDURULMUŞ KAVİTEDE DARBE İŞARETİ TARAFINDAN UYARILAN ALANLARIN ZAMANLA EVRİMİ

Öz

Bu çalışmanın amacı, plazma ile doldurulmuş ve mükemmel iletken yüzeylerle kaplanmış dikdörtgen bir kavitede, darbe işareti ile uyarılabilen alanların analizi için zaman ekseninde yeni bir yaklaşım sunmaktır. Başlangıç koşulları ile desteklenmiş zaman türevli Maxwell denklemleri nedensellik prensibi altında çözülmüştür. Plazma ortamı için Ohm kanununun dinamik versiyonu, plazma akımı vektörü ile elektrik alan vektörü arasındaki bünye denklemi olarak Maxwell denklemler sistemine ilave edilmiştir. Elektrik alan, manyetik alan ve plazma akımı için çözümler, kesin çözüm olarak konvolüsyon integralleri formunda elde edilmiştir
