主　　题：plasma sheath reflection and transmission flow field 

摘      要：The plasma sheath covering hypersonic vehicles has a significant effect on the propagation of electromagnetic *** on the calculation of the flow field of a conical cylindrical,this work studies the propagation of electromagnetic waves in plasma sheath at L-band and Ku-band,and discusses the propagation characteristics in the head,side and tail of the *** dielectric properties of plasma sheath are related to flight speed and altitude.A flight condition corresponds to a unique distribution of dielectric *** the conical cylindrical,the results show that flight speed is generally negatively correlated with the transmissivity of the plasma *** reflection characteristics of electromagnetic waves at the L-band and Kuband when obliquely incident to the plasma sheath show a downward *** the frequency is increased to Ku-band,the propagation characteristics of electromagnetic waves in the plasma sheath are related to the position of the sheath.
