We measured reflectivity on static stripe-ordered La1.84-yNdySr0.16CuO4(LNSCO)y=0.1, 0.2, 0.3, and 0.4 by means of reflective terahertz time-domain spectroscopy (THz-TDS) with electric field polarized alongc-axis, in which one can obtain lower frequency information than the conventional Fourier transform type spectrometer. Recently, two-dimensional superconducting (2DSC) property [tajima,schafgans,li], intra-layer perfect conductivity not accompanied with inter-layer superconducting behavior, was reported on LNSCO (x=0.15,y≥0.2). We observed the existence of Josephson plasma edge, which suggests that 2DSC is not realized in these compounds.
