OBJECTIVE
Examination of the effect of particle positionon PD induced EMW
characteristics.
Particle position: (1-5, X,Y,Z)
Examination of the effect of the presence oftwo PD sources at
different cross sectionon PD induced EMW characteristics
Particle position: (1Y-2Y, 3Y-4Y, 4Y-5Y; 1Z-2Z,3Z-4Z, 4Z-5Z)
Examination of the effect of the presence oftwo PD source at the
same cross section onPD induced EMW characteristics
