Tm. Roberts, THE NONLINEAR OPERATION OF A MICROWAVE CROSSED-FIELD AMPLIFIER - COMMENT, I.E.E.E. transactions on electron devices, 40(6), 1993, pp. 1188-1189
The title paper is significant because its claims of laboratory succes
s have motivated further use of nonlinear Schrodinger equations to mod
el amplifiers. Some of the paper's inaccurate equations are corrected
here, and others identified. Questions are also raised about the claim
s of success in the laboratory.
