Abstract:

This paper examines the negative-mass stability properties of an E-layer for transverse electric TE and transverse magnetic TM waveguide modes in a conducting cylinder. The analysis is carried out for a relativistic nonneutral E-layer aligned parallel to a uniform axial magnetic field B sub 0 e sub z, within the context of the assumptions that the electron motion is ultrarelativistic gamma sub zero 1 and that cube rt nugamma sub zero 1, where nu is Budkers parameter and gamma sub zero mc squared is the electron energy. One of the most important features of the analysis is that the axial energy spread can have a large influence of stability behavior for both the TE and TM waveguide modes. By appropriate choice of system parameters, it is shown that the spectrum of microwave radiation generated by the negative-mass instability can be very narrow-band. Author
