In a hydrogen plasma (T/sub e/ = 2.5 eV, T/sub i/ = 1.5 eV), excitation of ion Bernstein waves by an externally placed electrostatic antenna has been investigated for ..omega.. approx. = 2 ..cap omega../sub i/. Mode transformation of the electron plasma wave at ..omega.. approx. = ..omega../sub pi/ without observable reflection was observed, followed by strong excitation of the ion Bernstein wave. Detailed measurements of k/sub perpendicular to/(..omega..,k/sub parallel/) and of the wave packet trajectory show excellent agreement with theory.
