Краткий обзор статьи: The dependence of the Josephson plasma frequency omega_p in Bi_2Sr_2CaCu_2O_8 on a tilted field H is reported. Measurements over a large range of B and tilt angle theta allow a detailed comparison with a recent calculation by Koshelev. With a slight modification of the model, close agreement is obtained. From the fits, we find values for the in-plane correlation length and the zero-field critical current density J_{c0} (4,600 A/cm^2 at 30 K). An analogy to Bragg diffraction is described, as well as a picture for the fractional-exponent behavior of omega_p versus H.
