抄録	We discuss the dynamic response of odd-frequency Cooper pairs to an electromagnetic field. By using the quasiclassical Green function method, we calculate the impedance (Z = R - iX) of a normal-metal thin film which covers a superconductor. In contrast with the standard relation (i.e., R << X), the impedance in spin-triplet proximity structures shows anomalous behavior (i.e., R > X) in the low frequency limit. This unusual relation is a result of the penetration of odd-frequency pairs into the normal metal and reflects the negative Cooper pair density.
