The dependence of the Josephson plasma frequency 
in
on a tilted field 
is reported.
Measurements over a large range of B and tilt angle θ 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 Jc0 (4600 A/cm2 at 30 K).
An analogy to Bragg diffraction is described, as well as a picture for
the fractional-exponent behavior of
vs.
