Comment on ``Nonlocal theory of a whistler pumped free electron laser`` [Phys. Plasmas {bold 1}, 1025 (1994)]

In a recent paper [Phys. Plasmas {bold 1}, 1025 (1994)], the coupling of a whistler mode to a beam mode and a high-frequency electromagnetic mode was studied. It is the purpose of the present Comment to show that in that paper, the identification of a whistler mode in a waveguide (in the linear dispersion relation), as a transverse magnetic (TM) mode ({ital E}{sub {ital z}} mode) is incorrect, and that the calculated relativistic beam contribution to the dispersion relation is also incorrect. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
