Abstract

In this paper we investigate the excitation of longitudinal and transverse plasma waves in intrinsic Josephson junctions. We consider the outermost branch of IV characteristic (IVc) in current biased case and try to find the conditions in which plasma waves can be excited. We change the parameters of the system and get the corresponding breakpoint current at which the plasma waves start to initiate. We present specifically the modes containing only transverse waves where we can have radiation. As a result we find the range of parameters that the system can radiate.
