KeywordHollow Cathode Discharge Microwave Effect Large Plasma Sheet Density Distribution
AbstractA large plasma sheet 60 cm x 60 cm x 2 cm in size was generated using a hollow cathode, and measurements were conducted for interactions including transmission, reflection and absorption. With different discharge parameters, plasma sheets can vary and influence microwave strength. Microwave reflection decreases when the discharge current rises, and the opposite occurs in transmission. The C-band microwave is absorbed when it is propagated through large plasma sheets at higher pressure. When plasma density and collision frequency are fitted with incident microwave frequency, a large amount of microwave energy is consumed. Reflection, transmission and absorption all exist simultaneously. Plasma sheets are an attractive alternative to microwave steering at low pressure, and the microwave reflection used in receiving radar can be altered by changing the discharge parameters.; A large plasma sheet 60 cm x 60 cm x 2 cm in size was generated using a hollow cathode, and measurements were conducted for interactions including transmission, reflection and absorption.
