Abstract

Longitudinal Josephson plasma in high-T_c cuprates is formulated by using a intrinsic Josephson coupling model in which the charging effect due to the Cooper pair transfer between the layers is taken into account. The power absorption of microwave due to the longitudinal plasma excitation is calculated. It is verified that the sharp absorption peak observed in the microwave experiments in Bi₂Sr₂CaCu₂O_8+δ originates from the excitation of the longitudinal plasma.
